The net effect is that consumption (and associated demand) is suppressed at the lower to middle end of the income scale, where individuals' income isn't enough to sustain their needs + wants. When these individuals spend, the demand for labor + raw materials per $ spent is high, because they are often buying consumables or durables (food, washing machines, etc). At the high end of the income/wealth distribution, there are few needs that aren't met or exceeded, so their wealth ends up chasing assets and investments that induce far less demand for labor per $ invested. A the extreme end of this are private equity funds (billions managed by a small number of people).
