I have some further thoughts:
The problem of free market is that the price will affect the fundamental, investment capital will chase something that have continuously rising price, and drive its price even higher, so one after one bubble is unavoidable. You can only tell after it busted. I bought gold at 1300, now it is 1600, is it a malinvestment?
Apparently you decided that it's a good investment, the moment you bought it.
Why? Because you looked at the fundamental mechanism behind the price increase.
1) If you estimated a speculative bubble, then it's just that: you surf the bubble and try to estimate where the top is and take your speculative gain.
2) If you want to use the storage value of gold because you fear a demise of the fiat currencies, then you're just using it as a store of your wealth and sell the gold when this 'crisis' (please define 'crisis') is over.
3) If on top of that you think the exchange value is increasing because more and more people want gold for reason 2), then you may an added advantage from that.
But a bubble can not get big enough to let everyone become super rich, because FED is looking at the inflation all the time. When more people had easy money, there will be less people doing the real production, this will raise the price of everything, then FED will step on the break and freeze the liquidity.
... and create a mega crisis in the process.
Anyway, one of the characteristics of a bubble is rising prices. And how is price established? Because there is a seller, and a buyer who is willing to buy at the high price. This is already a guarantee that prevents that 'everyone become(s) super rich', because the buyer will become poor and only the seller will be rich. That is, during the last transaction (per item) that occurs before the bubble pops and price comes crashing down. So the last sellers become rich, and the last buyers poor.
Every investment have some risk, but there are different type of malinvestment. If people have lots of saving and doing malinvestment with savings, then the final result is just money transfered from some people to some other people, the purchasing power of those money stay the same, society as a whole do not affected that much.
Mwaaahh... I don't agree with the last part but I'm too lazy to comment
If people relies on the loan from the banks to do this investment, then they will not only lose their savings in the future, but also lose the interest they pay to the banks, so they simply select default and let banks take that loss. The bank holds many people and organization's savings, it can not fail, eventually government have to take over and becomes the biggest debt taker
Banks
can fail and banks
should fail!
Banks (even the federal reserve) are private companies with stockholders and directors who have the responsibility to take good care of the money invested.
If banks fail then the stockholders have been sleeping and let the boards 'play' with their money. As a result the stockholders lose their money.
No harm done. Government will bail out the clients through the PDIC and through the process of (finally) printing their own money to reimburse the banks' clients.
And the population can decide what they want to do: trust the remaining banks enough, or demand a government bank and do their business with them.
At least, that's how it
should be in
my opinion.
