Inequality by itself is not a bad thing. Let's start from there. If 90% of the population had a (sustainable) lifestyle of current dollar millionaires, and the remaining 10% had a (sustainable) lifestyle of dollar billionaires, there would be lots of inequality, but it wouldn't be problematic. Inequality is only bad if you're in a zero-sum game. The rich do have the power to extract rents and "rig the system" to ceme…
Extracting more work from the poor is often veiled under the guise of "improved productivity", so this measure of praise is not particularly helpful.
