The document discusses different types of taxes and whether they are fair. It explains that Social Security tax is proportional, taking 7.45% of income up to $90,000 but nothing after that, which some argue is fair. However, this makes the tax regressive as the poor pay a higher percentage. Income tax is progressive, taking higher percentages from higher incomes. Other examples of progressive taxes include luxury, cigarette, alcohol, and inheritance taxes. Regressive taxes disproportionately impact the poor, such as gas taxes. The document asks which taxes should be raised or lowered.
