Correct.
Add that the southern states were being taxed for canals and rails being built in the north for the mills...steel mills, textile mills...
The southern farmers were still having to pay to have their crops wagoned to the river to be loaded on a barge (there was a fee to use the barge) and then be transferred to a ship (another fee) to be taken to the mills in the north. Of course, there was a fee to get that load off the ship to the mills, too.
The southern states were wanting better rails, roads and canals to make transportation of their goods more reliable and less costly, using the monies they were paying already for the canals and rails they could not use.
In 1776, there was a great war fought over being taxed without benefit. US Revolutionary war.
In 1861, there was a great war fought over being taxed without benefit..a failed revolution referred to as a civil war. The spin that this war was fought to be finally rid of slavery (it was on its way out, already) is one of the best spin doctor moves ever. The Emancipation Proclamation was a psyop designed to foment rebellion amongst the slaves. The slave owners were not all evil. They had a vested interest in keeping their workforce healthy enough to work. Most treated their slaves "decently" as in fed, bathed, warm and ALIVE. Sure...sorta like the draft horse. The southern farmers were just some of the last in the world to use slaves en masse and so were like the kid that got the last piece of cake. He ate all of the cake. They were to be blamed.
There are slaves being used to this day.
Now, do not get me wrong. I am very much against slavery of all sorts. Most of us are little more than tax slaves now, paying taxes without benefit.
The USA is overdue a great war being fought over being taxed without benefit. Maybe we can spin it be rid of the woke bullshit going on.
