Answer 1

Because a few decades ago top earners paid significantly higher taxes than today, and income inequality was lower. Almost none of the productivity gains in the economy were captured by the low and mid income earners, while the costs of university education, healthcare and housing went up, to fuel corporate>shareholder’s wealth accumulation.
