Maybe also unpopular, but my standpoint on taxes is: The government is the one giving out the money in the first place. Every dollar comes from the Fed (exception some virtual money) like the monopoly bank just gives out money in the first place. 

The point of taxes is to keep the economy working fairly. Like putting high taxes on something to discourage bad behavior, and the other way around. Also, it's necessary to keep capitalism from evolving into feudalism, as money likes to accumulate on a few rich ones.

The second thought is what the government should with the money. Of course, they should do great and needed investments. Often times, this is not the case, but the root problems here are not taxes themselves. There is no alternative universe where the government is spending all money perfectly.

The real problem is the rich being able to evade taxes, and they frame taxes as something unfair. Additionally, not rich people pay far too much in taxes.
