An alternative to a capped income, would be that every income gets "inflated" by as much as needed until it reaches parity with big-tech incomes, which would require a kind of transnational union, but would have the effect of reversing the direction of extraction. Also, printing that money to inflate the income, would also cause asset-inflation, which also benefits people who own a life-changing amount of capital/assets. But _if_ you could cap asset-prices, then the inflation strategy might work. Note that I have not modeled this particular scenario yet.
