Wouldnt know what the OP refers to but silicon valley has been skirting regulations and running as close to a ponzi scheme as humanly possible, the likes of uber with blitzscaling, esentially growing their userbase with venture capital only to increase the amount of venture capital they can get to 'eventually' make a profit. Or SVB wanting to not be regulated because they hold less than 250B only to fail with terrible consequences. Then theres the numerous crypto startups that promise return on stake funded by new depositors to pay the old depositors. Money was cheap but in an economic downturn any weakness will result in investors leaving, cash drying up. So whoever cannot show profits will quickly wither and cause chain reactions in similar weak companies. I'm sure you can find an amazing list on hindenburg and you'll see most of them are tech companies because thats where the biggest venture capital pie was between 2008 and now.
