Taxes compound on one another too much. Income tax followed by sales tax followed by property tax, etc. We get taxed on the same money repeatedly.
Eliminate all tax aside from sales tax. Let people keep their money and spend it how they like. Income tax was only supposed to be temporary, and property tax is just seizing everyone’s property and charging rent. If we only have a tax on sales, then the government will be more directly incentivized to improve the economy.
(And while we’re at it, require businesses to show final price with tax included when labeling goods. Poor people have to deal with enough headache while shopping, they don’t need a sudden surprise fee once everything’s rung up.)
