I feel like if you care about taxes on capital gains you are rich enough not to care about taxes on capital gains.
If you want to comfortably retire, then one of the following is probably true:
1. you have a solid pension
2. you should care about capital gains taxes
3. you're REALLY rich and don't care.
No, I'm not rich, I'm just an entrepreneur, so most of my income is from capital gains. And most (almost all) of my expenses is paying salaries and vendors.
