First really thorough analysis of this situation that I have seen. It is surprising that this observation isn't more common, it is very obvious from looking at sectoral balance sheets...but, I suppose, not many people do this (it is odd to me that what was done during the pandemic had literally never been tried before, there was no economic logic for doing so, and no economist said: hold on, is this a good idea? And still, just a crowd of nodding dogs...you can only rely on an economist for a convincing explanation of what was happened, never the future, never creativity, never analysis).
One point that I don't think is made clear. Because this problem is totally artificial, it isn't clear how you solve it. Clearly, prices are going to have to increase substantially to choke off demand. But even once you do that, there is a question in some industries of whether supply can increase at all. Some big industrials are trading on mid-single digit P/E ratios, they just can't get money (most are actually being incentivized to return this, repeat that: shortage of almost everything, the market is telling them...reduce supply urgently). There is a flood of money for "risk-free" investments and tech (read: unprofitable, never going to be profitable but has value because you might be able to convince someone that you will be profitable...eventually), everyone else is being starved to death. It is quite terrifying because the govt has managed to debauch almost every price in the economy. Nothing is working.
