What if: earlier cotton gin?

What effect would an earlier invention of the cotton gin have on history, say it was invented a century earlier? Would it allow alternative cotton superpowers, would America be too valuable for Britain to lose, would it the international slave trade ban be still born, or perhaps a non-slave cotton industry could be enabled through low cost labour?
 
Bad, bad, horrible.

Vast increase in rate of settlement in Georgia and the Carolinas. East and West Florida get permanent English populations entrenched before the Revolution, so they'll have colonial governments as well.

Value of labor skyrockets in the colonies, but from the 7-Years (cough French and Indian cough) War indentured servitude is right out. It'll be a decade at best before the increase is followed by an increase in voluntary immigration, so the first result will be that slave prices spike. That means more slaves diverted from the Caribbean to the mainland. The survival rate was much better in the colonies than in the sugar plantations, so the effect of the increase will be disproportionate - a lot more black slaves in North America. Plus since the islands usually got first pick, the involuntary immigrants will tend to be healthier than in OTL.

All in all, you are looking at the Floridas as real provinces (and possibly future states), a big shift of population, wealth, and influence to the southwest of the colonies, a bigger institution of slavery, and higher slave prices (which makes freeing slaves more expensive when it comes in vogue during any eventual revolution). In OTL only South Carolina and Georgia were adamantly pro-slavery during the revolution - when they represented 5% of the nation's population, and little more of its wealth. Even other future Confederate States were ambivalent, and many slaves were freed by their owners in the rush of freedom-shouting. This scenario will alter the political landscape in a manner that might be interesting, but will be unpleasant.

Unpleasant yes very. But it is actually hard to say if the early increase of slavery would also make it last longer.

If we are looking into a more populous south social dynamics would certainly be different. It would not take long for these colonies to realize that they might be better off without England. So Independence might happen sooner. However New England might not want to be associated with these colonies during the independence movements. It might stay loyal or we might see two or more separate independence movements.

England might also try much harder to keep the souther colonies under its control. And it might be able to crush the first series of revolts. Only causing further resentment from their populations. Longer, bloodier, and more chaotic independence wars are likely. Possibly something akin to OTL Latin American independence. Where the people who start it are not necessarily the ones that end it.
As for slaves more of them means any revolt is potentially much larger. They might as well take advantage of the more chaotic independence wars.
The there are also the Native tribes in the area. With England in control while the population expands westwards they will probably be better off at first. Some will become slave owners and their land might be more respected. However when the time comes like in OTL they will likely be forced into choosing sides, and fighting each other.

Over all it would probably be a very bloody early 19th century in the American colonies.

We would also have to take into consideration if and how Spain ends up using the cotton gin as well. This might provoke more Spanish settlement in Tejas and Louisiana (now in their control). So if Napoleon comes along later on, he might not get Louisiana.
