It's the other way around. FICA tops out at $135k. Past that your wages are taxed at only 1.45% (for medicare) more than any other non-capital-gains income.
You are forgetting the Additional Medicare Tax of 0.9% that kicks in at $200,000 (single) or $250,000 (married joint).
There is also the Net Investment Income Tax of 0.9% that applies to all unearned income when you hit those same thresholds, including but not limited to income that qualifies as long-term capital gains.
