And how this "send it back to the states" argument of yours work when it was attempted with the slavery issue, Senator Stephen A. Douglas? Those who do not learn from history are doomed to repeat it.
Slavery was dying out by the time of the civil war. So, by handing back to the states, the problem was solving itself. Had we kept to that, instead of having our federal government screw around with the matter, there would have been no more slavery... *AND* no civil war.
And thus, no concept of an income tax or a powerful federal government.
Once again, a good example of how federalizing matters always makes them worse; no matter how noble the intent or good the cause.
