If the issue for the inequality folks was genuinely inequality (of opportunity), they would fight regulatory entry barriers for workers & businesses, subsidies, bailouts, poor rule of law, inflationary monetary policy...
Instead, it's always just higher taxes & more government.
We envision a new institution, the Global Justice Fund to finance this sustainable convergence path. The fund would raise revenue via global wealth and income taxes to be used for climate investments, expansion of health and education, and building up a World Sovereign Fund.
The Global Justice Fund would average 10.3% of world GDP annually between 2030 and 2060 — compared with less than 0.4% currently allocated to development aid and international organizations.
