England and most of Western Europe had outlawed slavery at the time that slave owners in the colonies declared independence because they wanted to keep ownership of other humans legal. America was founded by slavers that wanted slave owning to stay legal and claimed taxation with no representation as an excuse.
This excuse is rubbish. Americans gleefully attempted to exterminate an entire race of humans that were already living here. They made an industry of importing humans to be owned goods while the rest of the world had decided it was wrong. At the most fundamental level, America is a racist country.
In last place. America did finally eliminate slavery, but they were the last to do it. Every first world country criminalised slavery, America last.
