If you're sitting on a retirement fund, that hurts you. If you're sitting on debt, that helps you. So it's much more past tax payers than future ones who are hurt by this.
On the other hand, decreasing the value of accumulated wealth is exactly what ought to happen here. We're not producing very much, and everyone will have less actual stuff. The question is how the banking system adjusts.
If we see deflation (prices go down, salaries go down, revenues go down), people will default on debts and other fixed obligations, and the whole thing blows up in structural damage from bankruptcies, mortgage defaults, layoffs, etc.
If we see inflation, a lot less structural damage happens.
COVID19 is destroying value. What the fed is doing -- inflation in the stock market to keep prices where they were -- is exactly what ought to happen. Inflation will continue to happen elsewhere in the system. The flip side is you don't want starving, homeless people in the streets -- that will destroy massive wealth. We'll deal with that with inflation too, most likely.
