To win the cultural and intellectual battle, Europe must now assert its values and defend its model of development, fundamentally opposed to the nationalist-extractivist model of Trump and Putin

How do people argue for redistribution in Norway 🇳🇴 vs the U.S. 🇺🇸?

And what type of argument convinces who?

South Africa remains the most unequal country in the world, with the top 10% earning 70% of all pretax income.

New study by A. Gethin & L. Czajka shows that inequality in 2019 was as high as in 1993.

Racial inequality reduced only because top 10% Black incomes surged.
