SEVERAL THINGS THE WEST SHOULD HAVE LEARNED DURING THE COURSE OF THE DEMOCRATIC REVOLUTION

and long before, throughout the course of history, really:

 

You don't enslave members of foreign civilizations and races, and then import them into where you want to live. Enslaving them where they are is fine.

 

You don't indenture them as servants within your own civilization, but it is fine to have them as servants while you are in theirs.

 

You don't accept too many, of any kind, race, religion, or ethnicity, as immigrants, ever.

 

One classic example of how this was considered best practice by a great power was Spain up to 1492. It had expelled the moors and the Jews by that date. That probably was considered by them a great success: 'Let them determine themselves somewhere else!'

Of course, a whig interpretation of history will find terrible problems with this course of events, but that is Whig history for you.
