At the end of the day, if you're a billionaire earned income is a teeny tiny part of your earnings and most of it is kept unrealized for tax purposes. As a result, the doctor or software engineer ends up bearing a 50+% tax burden while ultra high net worth individuals are lucky to pay even close to the LTCG rate on all their income.
The tax system is oppressive under the guise of being "progressive" but really it prevents social mobility.
