The problem is, the last two decades were marked by extremely low, zero and sometimes outright negative interest rates plus a ton of outright printed money that got blown up the arses of the big banks. Worldwide.

That money sought returns and found them in hypergrowth of increasingly dumber nonsense. First it was Meta (or back then, just Facebook), then Tesla, then during Covid cryptocurrencies and NFTs, and now it's AI... but now, there seems nothing to be the "next big thing" to sink money into when the old thing dies down in growth and expectation and matures. Maybe gambling, but that's not sustainable, the number of whales/marks to make money from is finite.

IMHO, we're headed for a very big worldwide correction to deflate the markets and hand back a lot of the money to the central banks where it can be taken out of circulation, and it will be an event larger than the dotcom bust plus 2007ff combined. But, unfortunately, the markets can stay irrational longer than a good short-seller can stay solvent...
