If protective tariffs were such a bone of contention then why was one of the first acts of the confederate congress the adoption of a protective tariff?
In the seemingly hypocritical South’s case, the income collected would be controlled by “them” instead of the “Union” which they thought had it out for them.
If your perceived “enemy” was collecting “taxes” from your labor and using those “taxes” to beef themselves up I guess you would get pissed. This was there main sticking point, how the dollars were distributed.
Whoops forgot, why did many “free traders” vote for higher tariffs after the South split? Same exact reason, to raise revenue quickly to fight.
