story
There is no free lunch. Eventually asset prices reflect underlying value - not too many dollars chasing too few assets. Eventually inflations forces higher interest rates and the value inflation disappears. Eventually bad assets are correctly priced and value disappears.
It’s like the financial crisis in 2008. You can go years with increasing prices, but if it based off false premises and not a true increase in productivity, then that value eventually disappears. If it happens suddenly it has massive ripple effects through the economy.
