I get that there are a lot of people with special types of jobs where their specific financial circumstances or the way they earn money is unusual. In that regard, I get why those people need to file their taxes.
But what about the remaining vast majority of people with standard jobs? The government absolutely does know how much I make and it makes zero sense for us to have to fill out a bunch of paperwork and not make a mistake on something that the government already knows the right answer to.
