A flat tax implies equal percentage rate of tax. That is an equal burden. Any tax levied on a poor person is a burden, but poor are not exempt from civic responsibility.
The poor pay more taxes, indirectly and directly, expressed as a percentage of net worth, than the rich. How so?
If a rich man's holdings on 100 million in assets accrues to a value of 120 million, his net worth and increased $20 million but was taxed on 15% of income, not wealth, which could be a very low figure, given loopholes which, by comparison, that 15% represents a small fraction of that compared to his wealth accrual. The system is vastly in his favor.
Poor people pay direct taxes in other ways, they pay a payroll tax, they pay sales taxes, etc.
But, a poor man who has $500 in the bank, whose income does not keep up with inflation, pays an indirect tax due a decrease in purchasing power.
Where does the value lost by the poor via inflation go to? It goes to inflation's beneficiaries, the government ( because they are the creators of inflation via fiat currency created faster than GDP can keep up ) and the rich who can hedge against inflation and profit from it. Inflation is a transfer of wealth from the poor to the government and to the rich. When you print money, value is not created out of thin air. What it does is shift resources from one sector and passes it to another. I understand the complexity of money creation, and all that, just keeping it simple.
Poor are more likely to be given welfare in other matters.
The rich receive welfare via inflation benefits, tax breaks on corporations, low capital gains tax, and any tax they do not pay and should, that burden shifts to poor and anyone who are unable to shield themselves for lack of investments. Also, Churches and non profits do not pay taxes, and I believe they should ( maybe at a discounted rate, but they should pay taxes, in my view, because they benefit from government services, too, just like everyone else ).
I know you are going to argue that inflation is technically not a 'tax', but money is money, value is value when it goes out of your pocket and into another's or a poor man loses purchasing power because of inflation while the rich get ahead of it, it feels the same. It's not a tax in the
de jure sense, but it is a tax in the
de facto sense.
There should be a motivation to exceed not become complacent.
There should be motivation to prevent the rich from exploiting the poor.
'exceed'? You mean 'excel'. That motivation already exists, it's call misery of being poor.
FYI, 15% to a poor man is far more painful than 15% to a rich man. No way in hell is that an equal burden.
What I find is that the vast majority of people on the right are unable to grasp the principle given in this post.
Some libertarian economists, do, however.
