I would be willing to bet, if you take away the money the politicians steal, the money being sent to other countries we get absolutely no benefit from, and money spent funding sin and abominations here in our country most Americans would absolutely be opposed to, and spend our tax money instead on the services it was meant and advertised to be spent on, income tax would not be needed, likely the services would be better, pretty sure it all could be paid for on the current sales tax. If tarrifs were added that are fair, considering the particular circumstances, i believe the govt services we legitamitely need and use would be improved dramatically. I dont know about doing away with the IRS, our country needs some sort of accounting service but it could absolutely be streamlined down to probably 10% of what it currently is.
