Adding in that the economy was partially parked up through COVID and the risks of being shut down by the government turn out to be much higher than people realised hitherto.

Not many are crazy enough to put lots of money into low-margin businesses that are at high risk of being shut down. Capitalists are greedy but not stupid.
