Do you consider sales tax, etc as tax?
Sales tax, gas tax, land tax, etc all come later. They can be significant, but aren't part of the discussion of take home salary.
To look at it from another point of view... If _all_ the money you made came from long term capital gains, the taxes you pay on it would be based on totally different tax rules. Capital gains taxes are certainly impacting how much you "spend" on taxes, but they don't impact how much of your "salary" goes to taxes.... because you don't have a salary.
