If our income is to be taxed, there should not be different tax rates for different tax brackets. Rather, there should be a flat rate for everyone.
If the whole population is taxed at 10% then those who make $30,000 and those who make $1,000,000 will be taxed proportionally.
There are hesitations regarding entering a new tax bracket and making more money because the raise can feel so small when it means you’re now giving more of your money to the government. This would ease that tension and encourage swift upward movement in the job market and when it comes to innovation of new products.
