It's policy, like lowering interest rates, promoting financialization, driving people to invest their savings in the stock market, squeezing out basic saving strategies and causing people to seek higher and higher risk investments (while socializing the risk of the upper class) that's driving a wedge.
100% of this is public policy (often in the guise of helping out main street "saving jobs" e.g.). Capitalism is just responding, but as always with unintended but predictable consequences.
