Never heard of the Laffer curve, have you? Arthur Laffer's theory, since demonstrated, is that there is an optimal point of taxation that maximizes your revenue. Go above that rate and the level of taxation discourages economic activity and actually results in lower tax revenues.
It's this type of thinking and philosophy that is utterly, utterly frightening folks. It's totally against free trade and capitalism (Valligndigham was a notorious free trader and that's why he opposed the Civil War).
Vallandigham was a well-known advocate of state's rights and didn't give a damn about free trade.
Raising tariffs on imports favoring one business over the other and that's something that to me, the govt should stay out of. I like free trade, even if you do not.
Or Jefferson Davis either. He signed the protectionist confederate tariff in May 1861.
