I hate Woodrow Wilson as much as the next person, but most income taxes around the time of WW1 were imposed by a prohibitionist called Wayne Wheeler. He literally made his political opponents disappear, and the income tax was most likely because alcohol taxes made up around 40% of the countries income.
I also hate that government funded things are often very inefficient, but taxation is still necessary. It is not given to 'every foreign country', but is either spent on oil (Which I don't like either), or given as humanitarian aid to underdeveloped countries. Idiotic research happens, yes, but without taxes, you wouldn't have an army, the roads and other things owned by the country would be in a terrible state of disrepair, the US would've lost the space race, etc. You clearly have no idea how much taxation has benefitted the nation. The democrat party is not, in fact, an anarchist party, but the anarchists are actually more right wing than left wing.
