The world’s population is about 8.1 billion. The top 1% of that is 81 million. The population of the G7 (a reasonable substitute for the richest countries) is approx 800 million. So, if you’re in the top 10% and in a G7 country, you’re in that top 1%.
Top 10% income in the US is approx $170k per year. That’s mid-level manager wages.
