I think the other lesson we could draw from America is that we shouldn't let everyone in, they'll kill us, take our place and feel bad about it a few hundred years later... maybe.
Adding that detail, the situations are a bit more apples-to-oranges.
The circumstances are obviously different, and the sarcasm was my point too: the situation then isn’t the situation now, you can’t possibly hope to compare American history to contemporary Swedish reality. It’s like comparing, as you said: Apples to Oranges.
