As I frequently try to point out, wealth inequality seems to only meaningfully decrease during market corrections, which the Fed is determined to prevent at all costs, despite the side effect of increasing wealth inequality (which could be a feature rather than a bug) [0].
The more the Fed distorts normal market signals, like interest rates, the less efficiently capital is allocated, and so the wealth distribution morphs from one that roughly represents human skill at allocating capital to an extremely top-heavy skewed chart that rewards incumbents.
