Oh, a lot of banking regulation introduced after 29 was rolled back in the 90s and 00s and not restored after the 2009 Crash.

I was actually in Investment Banking before, during and after the 2008 Crash and unconditional rescues with no lessons learned were all the rage.

That said, my point comes more from the economic super-cycle which takes about an century and is mostly visible in terms of general indebtness. This stuff has to do with the nature of economic activity in general and risk aversion (or lack thereof) by economic actors, so it's way beyond mere stockmarkets and their crashes (which reflect it rather than drive it).

There's a lot going on with anemic growth and the "solution" for the persistent recession after the 2008 Crash - ultra-low interest rates - being rolled back due to an accumulation of bubbles all over the Economy leading to Inflation (which was already going up before the war in Ukraine), in turn causing rumbles in the realestate mortgage market and the more bubbly stockmarkets like the Nasdaq (and even more in the Tech Startup investment asset class).

I mean, we're even seeing the rise of populism in politics.

I suspect we might be living in interesting times.
