The vast majority of the announced layoffs were white collar jobs, people getting $100k, $200k or more per year. That does not fit the story of rich getting richer, does it?
The Fed raising rates results in bonds losing value. Equities too. Real estate too. Other less liquid assets too. The vast majority of the rich in the US have lost money. Not so much the poor, because the poor don't have a lot of financial assets. It does not mean the rich have become poor and the poor rich, it just means this is not one of the times when the gap between rich and the poor has increased, or that the Fed is working diligently towards increasing this gap.
