What's the argument for and against using a flat tax?
assistant
For:  A flat tax is easier to administer than an income tax, which means it’s more efficient. It also eliminates deductions and credits, so people pay taxes based on their total income rather than what they owe in specific categories.2 Against: A flat tax can cause some people to pay more in taxes than others with similar incomes. Also, since everyone pays the same rate, those who make less money may not be able to afford certain things that are now taxed, like healthcare.
