I think someone else needs to do his homework. Since Abe Lincoln used an income tax to pay for the civil war. But hey he instituted an income tax during that time, so he was a terrible president.I believe the only time we had an income tax previously was to sponsor WW1. That was hardly routine.
The tariff info is widely available and doing your homework won't change anything.
As far as the income tax of the 1910's, no I don't think that percentage would be fair, we have to pay for all the spending the people you keep putting into office.
