remember where they live too. that high income means a near 60% tax rate on the earning side and another hit when they buy anything on the sales tax side.
Its a good problem to have, they will still be wealthy, but its not the numbers people throw around as if each employee got a large % of the game's earnings to keep, directly.

if I paid you a flat million to mow my lawn in the USA you would be lucky to keep 1/4 of it after all taxes were applied in the highest areas.
