The capital gains tax is a tax on the very inflation that governments cause

$100 invested in 1984 without any increase in actual value would be worth $266 today, so sold at break+-even, the imaginary but taxable capital gain would be 2/3 x 166, or $111.

Therefore, even if you broke even -- the investment made zero -- you are being taxed on recovering $111 of your own pre-tax invested money.
