Tax Rates on 75K income in the US: 19% (take home 60K). In Germany on 50K: 35% (take home 32K)
What are you waiting for, exactly? America is profoundly, almost absurdly prosperous. Truck drivers here make more than software developers in many "modern" countries, even in spite of the fruits of remote work.
edit: aredox in replies has even better proof of mass American prosperity vs the rest of the world over the last 20 years. It shows 10th, 50th, and 90th percentile incomes all shooting up for the US and the major European nations mostly stagnating, especially for the 10th and 50th pct populations.
