Yeah, rich folks hire accountants and tax lawyers to protect their money from folks like Strk. Big suprise there, right? Because ~37% isn't enough and 49% won't be enough and eventually 63% won't be enough, etc., etc., etc.
Do a little research, the Swedes did. See what the found out happens to your tax system and economy as top tax rates approach 40%.
The gist of it is that people, even rich people, don't always act like cows to be milked.
So ~37% isn't enough for you to feel figure they are finally paying at "higher level of support to the system" because they can afford tax accountants?
How much until Strk figures they "give a little something back"? Obviously ~37% isn't enough.
