In another comment you shared a avenge bus driver salary as 44k/year. So by your statement, your friends would earn 4x that, meaning 176k/year while you said you earn 6x that at 264k/year.
Sorry, but something is wrong here. Either you're data/math is wrong, or you and your friends work in the top 1% FAANGs/big-tech jobs, because those tech salaries aren't the norm in Europe.
