It's almost as if this is a complex system of human behavior and incentives that spans an entire society. That being said, if you pay attention to what's going on, it's fairly obvious to see.
Gens Y and Z make up the largest population cohort in the US by size, but hold only 10.5% of total wealth in the US. Baby Boomers hold about half. [0]
Baby Boomers are of retirement age. That means that many of them are drawing off of retirement accounts. Since you can't save for retirement without compensating for inflation, you have to find ways to grow the money. Most people do this through investments backed by stocks and bonds.
Stocks and bonds derive their value from the labor of the people working at the organizations that issued the stocks and bonds. More and more, those people aren't Baby Boomers. They're retired.
So that money is coming from people who are still working: Gens X, Y, and Z.
To increase returns on those stocks and bonds, you have to reduce the amount of money going to the people doing the work so that they can go to shareholders. Those shareholders are often people with retirement accounts.
