NO TAX IS FAIR.
NO TAX CAN EVER BE FAIR.
Taxation is violent taking by its very nature.
Pragmatically necessary, but violent taking nonetheless.
If I am a robber and go to person A and rob them of all their money, then go to person B and rob them of only a quarter of their money because they are poor, I donât think either person would consider me to have been fair. 
The government is not being fair and cannot be fair.
Rather it is the governmentâs task to equitably distribute the tax burden in a way that allows them to raise their desired revenue stream, while at the same time trying not to disrupt the economy more than necessary.
Obviously, in over 220 years, the Federal Government has not mastered this and the States and localities even less so.
Unearned income is a big and overinclusive term and different types of unearned income can and should be treated differently.
Long term capital gains are rightfully taxed lower, to encourage future consumption âsavingsâ over current consumption. This is a tried and true concept and should not change.
We do graduate income tax rates and provide a generous standard deduction to protect low income earners.
I am well into the 37% tax bracket and have to write four quarterly checks of five figures each to the IRS every year, plus a smaller check with my return.
But I recognize that I and others similarly situated have the ability to absorb this tax burden while those below me do not.
That is why we have 10%, 12%, 22%, 24%, 32%, 35% and 37% brackets that form a curve at the bottom of the income ladder and are supplemented by a generous standard deduction.
This system is not at all inequitable to the poor.
Needs work of course.
But not the worst system.
