Yes, the value system was the same Binnie, but people change...and countries evolve. The North descended from the Mayflower just like the South did, but they evolved.
I would even go so far as to say that the South may have shared all but one value in common with the original 13 colonies (half located in the North East btw), and that was the South's willingness to break up the Union to make a point. One of the main values of the original founders was the importance of maintaining the Union.
Now we all here might disagree on what that point was, whether it was the right to hold onto their enslaved captives, or something else.
Really not trying to pick a fight, but the north had a larger population and was mostly industrialized, meaning they didn't need slavery unlike the south which was more rural and into agriculture. If you are going to feed the entire nation which is mainly where produce was coming from at the time, you need the manpower to harvest thousands of acres of land. NOT trying to defend slavery just pointing out the facts.
