I think the biggest damage came from effectively zero-interest loans to those with means: high net-worth individuals, financial institutions, etc.
Insanely magnified purchasing power for those with access.
Consider housing. Blackrock and the Google Squad hoovered up a ton of real estate and converted them into rentals. Normal people can't offer 20-40% above asking for a home, so they were priced completely out of the market.
Starter homes have doubled or tripled in price over the past four years. Salaries have not risen to match.
Same is true for many other goods, and when combined with deliberate supply chain sabotage at the behest of the ruling class, effectively turned a significant chunk of the population into serfs overnight.
The knock-on effects of this aren't going to be pleasant.
People take pride in their work when they have a future to build towards. That no longer true for younger folks, or even a lot of people in their prime working years, so everybody is just sort of... phoning it in.
Imagine you're a high school graduate today. All you can see down the road for you is an either an infinite series of "gigs", or, if you're lucky, the luxurious serfdom of corporate servitude. In the latter case, you still don't earn enough to ever own property, but you get free food and access to approved activities from your masters in the company hierarchy.
