I would more correctly say we inherited it from a world tradition for four or 5000 years at least. We were the people who broke it and killed over half 1 million of ourselves in the process. Some will argue with the Brits started abolition. What they were actually doing was removing competition. When they were busy growing about abolition, they were running into like one giant plantation, and moving coolie labor around the world, which is still slavery with a slightly different structure.
Every major world power has had slaves, some still do. Regionally, every strong country has had slaves, some still do.
This statement would be inaccurate, it cannot be correct.
Massachusetts was not a colony of Mesopotamia.
Maryland was not a colony of ancient Greece.
New Jersey was not a colony of Spain.
Virginia was not a colony of Egypt.
Connecticut was not a colony of China.
Rhode Island was not a colony of Persia.
Etc etc etc.
All thirteen colonies were singularly colonies of Britain.
The only small exceptions might be, maybe, that New York started out as Nieuw Amsterdam and a few others had small influences as well much much earlier, but by the time you get to 1700+ all thirteen colonies are long dominated and singularly British. So you got the Netherlands in there.
So no, it cannot be said of some "everybody did it" 5000 year tradition.
"Some will argue with the Brits started abolition"
Some do, but they are not correct, that is only a historiography and not history. The actual historical record and the documents shows that it was the Americans who started abolition. We did that. That's our fault. Abolitionism was American, not British.
Another point to celebrate, as Americans. Of course. We were correct.
