>There is not much investment because profits are quite high.
There's no direct causal relationship between profits and investment. There aren't any companies that think "you know what? we've got enough profits for now, why do we need more?".
There are plenty of companies who see tapped out markets that aren't growing and decide not to invest.
Indirectly I guess the accumulation of wealth at the top via profits is party responsible for no money at the bottom to buy products and services.
>Decreasing wealth inequality is an end, not a means to an end. If you want a stable economy, focus on prices: inflation and deflation.
That's exactly what the fed has had its laser-like focus on for the last ~20 years. Stable the economy was not. Prioritizing inflation while inflation is under 15% is simply prioritizing the needs of those who don't work for a living over those who do.
>If you want a functioning society, focus on income and employment. If you want both, then you get the Federal Reserve.
The fed only really cared about inflation in the last 20 years in spite of its mandate.
