Germany is 87% not just white but European white. 74% of those are ethnic Germans. Gini is 0.816
Canada is 72.9% European white and Gini is 0.728
The U.S. is 60% non-Hispanic white and Gini is 0.852
These numbers don't capture everything (e.g., distribution going in to Gini is important), but they do capture a lot. I think the conversation could do without the race-baiting, too :-(
