And you have to remember that life is cheaper in Poland and earnings are lower accordingly. If https://www.numbeo.com/cost-of-living/rankings_by_country.js... is to be belived it could be thought as $270k for USA average and around $346k for San Francisco.

But salaries are lower then that. With data from Wikipedia for Gross Average Wage the sum goes to around $646k. Also I believe Polish artists will earn much less than their American counterparts.

how many Rogans is that?
