Then you should learn more about it. You never heard about it does not mean it is not happening.

我又真係好有興趣聽吓你有啲乜野歪理咁巴閉呀？First year econ 喎？實際、行得通嘅話先再講啦？極其量咪又係叫你轉手賣咗架車俾人，然後用返賣車果筆錢來買新車之類？

再唔係就話要睇吓架車係長hold定係短揸，短揸就無所謂，長hold就咪掣。但家陣個比喻係國家，有得賣咗個國家俾人嘅咩？你想賣俾美帝、東瀛、定係事頭婆？（話說回頭，請返中華民國重返大陸掌權嘅話，我又舉腳贊成呀！）

Come on, baby!我等緊你嘅「高見」呀～

P.S.  Lik, the "car" question is a genuine exercise question from an economic textbook.  
The lack of economic knowledge should be one of the reasons why your view is so limited and narrow minded.

If these egghead economists are all so smart, the US and the world wouldn't be in such deep trouble now, would it?

Theories are all nice and dandy, but only until they face the limitations and restrictions imposed by reality. By their very nature, theories are only drawn up by people bounded by the theories' assumptions and the author's presumptions and believes. This is especially true in any of the non-science science subjects. Case in point: free market theories also dictate that things will self-regulate, but do they? If academics weren't completely out of touch with reality, why else would they be called living in the ivory tower?

Any reasonably intelligent university graduate with a few years' worth of work experience will tell you that those theories you learn at school only serve as the minimal basis of your knowledge. At a rudimentary level, they work, and they help you analyze the situation methodically. But once you start factoring reality into account, everything changes.

I'd really like to hear what kind of bs "textbook answer" you have for your old car question because I will shred it apart in no time.

Enjoy living in your own little fantasy university la~

Why don't you just read the first 3 chapters of the first economic course before BSing about the uselessness of economic theories?

回返正題，最新報導話悅悅腦幹未死，即係仲有得救：

悅悅父﹕醫生稱腦幹未死

【明報專訊】女童悅悅父親王持昌透露，醫生澄清女兒尚未腦幹死亡，雖未脫離危險期，但也令他心頭放鬆了一點，「心底當然希望她再蹦蹦跳跳，只是現在最希望她腦袋好起來，手腳方面遲一點再說，讓我們好好照顧她，教懂她日後努力面對。」

盼日後教女兒努力面對

兩歲的悅悅仍躺在深切治療部，被剃光頭，小小頭蓋骨暫被移除，由紗布包裹，插滿喉管，以助呼吸抽出內出血；她左手包紗布，被單尚有血漬，醫護忙檢查。王父說，小孩子聽不懂打氣說話，「我只是在她耳邊輕輕問，你不是很想跟哥哥爭玩具嗎？快些醒過來……」

王母一直蹲在病房門外，王父指妻子心情未平復，而7歲長子一直在家哭鬧，嚷妹妹不見了，「他年紀還小，只是哄他妹妹跑了去玩」。

王先生在車禍現場附近開五金舖，他憶述當日下大雨，他正埋頭工作，工作桌剛好遮住女兒的身子，妻子忙收衫，突然大叫不見了女兒，兩人嚇得四處找尋，未料女兒才2歲也懂避雨，走了平常不會走的路，令他們撲空，「我寧願放棄所有，只想一切沒有發生」。

天朝御醫連老江明明死咗都可以救得返。如果兩者只能選其一嘅話，我一定會救悅悅而唔救老江。

「冷血司機」被揭假冒

【明報專訊】廣州《羊城晚報》前日報道，有一名自稱是肇事司機的人致電悅悅父親，態度惡劣輕佻，並說不會自首，該報道被中港兩地傳媒廣泛引用；但該報昨證實此人偽冒肇事司機，是惡作劇一場，肇事司機已向警方投案後，這惡作劇者的電話仍能打通，被拆穿後就一直關機。

被拆穿後關手機

悅悅的父親王先生事發後曾經公布自己的電話號碼，徵集破案線索，但未想到有人以此取樂，在傷口上撒鹽。這名惡作劇者的手機號碼來自西安，自稱肇事司機，「想給一萬塊錢私了這件事」，其間他還指悅悅走路不看路，自己「絕不會自首」，會逃往新疆云云。

之後該男子接受《羊城晚報》及廣東電視台採訪時，仍以肇事司機身分自居，態度囂張，甚至在電話中笑出聲來。悅悅父親信以為真，曾不斷致電拖住他，並趕到佛山交警支隊報警，但經警方查證，真正的車主較早時已歸案，該名無聊男子後來得知被拆穿後，就關機了。

一個父親慘遭女兒性命垂死嘅慘劇，竟然仲有人可以呢個時候響傷口上撒鹽，如此人渣，真係唔死都無用！

車，以為有乜野咁把炮。你夠膽講 opportunity cost，我就更加肯定我可以KO到你個垃圾argument一棟都無。有料到嘅話就成個理論講晒出來，等我同你逐點擊破，睇吓你有咩辦法來解釋繼續 keep 架車、年年 dum 錢落去整先至係上算。而且我已經立即可以應承你，我一定會用返 opportunity cost 呢個概念來 KO 你。

天下間根本就無啲咁戇車嘅「邏輯」去一直養架年年要大修嘅爛車，而共慘黨亦本身就係不斷蠶食中國嘅禍胎。

Ok, I'll take your answer as:

The opportunity cost to sell the car is too high because of... whatever reason

Now, preicsely, what are those so called reasons that you claim? If you even dare to cite any one of them, I'll rebuke it with a counter argument so strong that it'll knock you out of your socks.

But I'll give you a taste of the stupidity in your so called flawless reasoning here: If the real world really works like that, everyone in this world would be driving old clunkers from the 1950's because "the opportunity cost to decide whether we should buy or sell the car is too high".

I think you should really be the one to take your own advice:

一個從不敢承認和面對自己的無知和錯誤的人，絕對不是一個勇士而是一個懦夫。

So that's your answer, huh? That the decision process to sell or keep the car amounts to too high an opportunity cost, so instead of making the effort to make that decision, you simply just blindly press ahead with the decision to repair it?

That is the most ridiculous answer I have ever heard. Honestly, I expected more from you.

Let's look at the "cost" of making the decision to see whether you should fix the car. The general rule of thumb to stop repairing a car is when the cost of the repair exceeds the market value of the car. Since you already know the car is only worth $5k, but the known service and maintenance cost will already cost $2.5k a year, in 2 year's time, you would have spent as much on the car as it is worth, thus meeting the criteria to stop fixing it.

But then there are the unknown costs. Since it is an old car in need of known repairs, additional parts are likely well worn anyway, and would easily fail. That would add to a yet higher monetary cost. These repairs could be big or small, but they'll ding you neverthless. So your total out-going sum over 2 years is gonna be way over $10k. But by then your car won't be worth $5k anymore. Over a 2 years period, it's quite reasonable to see the car depreciate a further ~$1k a year, so the car is worth $3k. So you have:

($10k) + ($??k) (unknown repairs) + $3k =  ($7k) + (cost of unknown repairs)

And we still haven't factored in the cost of your time and inconvenience when the car breaks down, and you have no car to use.

How, how much would a new car cost? You can buy a brand new and reliable car for as little as ~$15k. Repair costs are extremely small because the car is new and reliable. That is not to say there is no risk in the car needing repairs, but the chances of those are slim, and the repair would likely be covered under warranty. You may have to do a bit of research and car hunting, but in this day and age, Google makes that painless and quick. And with a new car, you get the latest safety features and better fuel economy to boot.

So it boils down to:

total opportunity cost of old car:
$7k + unknown repair cost + inconvenience from planned and unexpected down time

total opportunity cost of new car:
$15k - benefits you gained from having the latest safety features - benefit of peace of mind in knowing that there'll be a minimal number of surprises

As a rule, humans hate the unknown, and it costs additional stress and anxiety. Also, the cost of unknowns will usually turn out to cost more than what we expect.

So did that take long? It only took me like 10 min to type it all out.

Now, moving on to the CCP. The social costs of continuing to have the CCP around is astronomical. With 1.3B people living under its rule, how many people have suffered as a result? How many more incidents of little girls getting rolled over do you want to see? How many different types of new poisonous food do you need to eat (and get sick from) before enough is enough? As long as the CCP stays in power, there will be no end to the Chinese's suffering.

Actually, I forgot to include a very important point that I was going to include, but have somehow forgotten.

At the end of the 2 years, your brand new car is still gonna be worth a good chunk of money. Even if you factor in a depreciation of 30% (which is probably too much for a 2 year car), the car is still worth a good $10k. So essentially, the total monetary cost of a new car alone is only going to be $5k, and then you still have the intangible benefits.

So, here are the monetary TCO alone of keeping the old junker vs buying a new car, and I am not even considering any intangible benefits, nor the amount of money you get from selling the old junker before you buy the new car:

TCO of keeping old junker
($5k cost of car) + ($5k cost of repairs over 2 year) + $3k residual car value = ($7k)

TCO of buying new
($15k cost of car) + $10k residual car value = ($5k)

As you can see, at the end of the 2 years, you would have spent $7k had you kept the old junker. If you bought a new car, however, it would only have cost you $5k. If you include the intangibles, the argument to buy new would be even stronger.

Now, Rocky, with cold hard numbers staring right at your face, come out and admit that you have no clue what the proper answer is to your own question. You toss around big words like "opportunity cost" as though you know what you are talking about, but in reality, all your calculations and estimates are completely off base.

The same goes for your evaluation on the CCP. By way of your car selling example, you were essentially trying to establish that the opportunity cost of keeping them around would be lower than getting rid of them. Clearly, you are completely wrong.

Now shut up, go learn some manners, and try to learn a few things from me before you try to show your face around here again la.
