Let's say you skewed income distribution a bit more like 1950s US, when high marginal tax rates resulted in more equal distribution of revenue through mechanisms like deductions or simply not taking that extra bump from 3 to 4 million. Now the upper 1% has lower income, but they were already mostly not-limited in purchasing power by their income. The upper 5-10% gets more. They go out to eat more, etc, etc.

We tried that experiment after passing "soak the rich" taxes in the early 20th century, and it seemed to work out pretty well for economic growth and living standards. But then we moved back towards "let there be oligarchs with immense wealth" instead. One of the claims was that the "investments" from allowing the powerful to keep most of the revenue streams for themselves would foster enough development to make it more than worthwhile, but instead... the broad base of consumer spending power has tanked, so businesses to supply the masses haven't found spending power to justify new investment/development outside of ad-powered ones participating in an arms race for the constricting consumer spending power that remains (or those industries benefiting from wildly subsidized-in-weird-ways spending like healthcare/pharma). And so it has also inflated asset classes across the board as there aren't enough startup ideas to eat up all the investments because of the general decline in spending power. Which hurts spending power further. (IMO the ability to capture higher and higher amounts of corporate profits as personal income also correlates to the massive financialization, outsourcing, and other short-term number-juicing moves we've seen.)

We can point to a lot of problems that have occurred from taking revenue shares away from the average worker, so it shouldn't be rocket science to think that returning a greater share of revenue to workers would return some purchasing power and guide the economy back towards development and growth instead of zero-sum asset bubbles.
