I agree. However, many people, both low and high income, know absolutely nothing about taxes and tax forms or how complicated or not complicated their tax situation may be or how much effort they'd spend on tax filing. People are taught the tax code is really complicated and they are really worried about screwing up. Furthermore, TurboTax has become so big that many new filers just kinda think "Do Taxes = TurboTax" without really considering that they can do it without tax software.
