The problem with expansive monetary policy is it trickles down, but not much gets to the bottom. Stock goes up, but workers not invested in the stock market don't like it going up. Everyone who already has stock gets richer, and buys real goods and assets. When those goods are produced overseas or by automation, not much makes it to wage workers.

Eg the last 2 years where people saw their 401k double, and cost of goods and housing went up.
