A salaried employee pays income tax on essentially 100% of their pay, every single year, automatically withheld. A lot of wealthy individuals' net worth grows completely differently — mostly as unrealized capital gains (stock and business value that's gone up but hasn't been sold), which the tax code doesn't touch until an actual sale happens.
Long-term capital gains (on assets held over a year) are also taxed at lower rates than top-bracket wage income — a real, long-standing, deliberate policy choice in the tax code, not a secret loophole.
Split $500,000 of income between wages and long-term capital gains and see how the blended effective tax rate changes. Uses approximate current top US federal rates (~37% top ordinary income, ~20% top long-term capital gains + 3.8% NIIT) — illustrative, not tax advice.
Correct moves you up, wrong moves you down — reach 100 to master this lesson.
