RP Story Help

So the American I have does not have Texas or the south west. The current year is 1970, and the nation never had a civil war. Why? Because through various compromises in the south’s favor, and the Corwin Amendment being ratified, slavery has continued in some form or another up until the present. Civil rights is now going on for FREEDOM blacks, but some are still enslaved and have no hope of freedom as it’s in the constitution and no one wants to push to unratify it. The south is much more populated along the Mississippi, along the coast, and Georgia is just massive.

So my question is, what do you think modern 1970 slavery in America looks like? Keep in mind the fugitive slave acts are passed, so slaves don’t just become free the moment they go north. Also, Texas is a slave owning country too, and it s allied with the US so like, slaves don’t just cross the southern border in droves.

I’m assuming the whole plantation style system has been aged out with better farm tech and the realization that slavery just is more expensive. However in assuming about 1%-5% still own slaves in slave states.

New Orleans. Memphis, Vicksburg, Atlanta, Nashville, Asheville, Charolette, Raleigh, Charlestown, Jacksonville, and other southern cities are much larger than IRL. Black Codes and Jim Crow laws still apply to freed blacks.

Long story short, what form would slavery manifest today? What would the life of a slave be like?
