In the case some founding fathers, quite literally. Or rather who you own works for you as long as they exist.

If the anti-slavery states hadn’t compromised with the slave ones, the Revolution would have failed. Slavery would have likely existed longer because the British would end up being allied to the slave states (likely still colonies.)

Nothing is more nauseating that modern people looking upon the past with moral superiority.

Didn't the British abolish slavery before the US?

The British could abolish slavery because they no longer had any real economic incentive to keep it, as they had lost their colonies. They also then proceeded to exploit labor in India in barely better conditions.

If Britain retained its American colonies (because the slave holding ones didn’t join the revolution) then abolition might not have happened at all.
