Ah yes, the "if you don't like it, you can go back to where you came from" argument, in different clothing of course. This is just never a good rhetorical device. What a person did or did not benefit for is up for debate -- even North Korea provides basics -- but that's not what is being argued here. If I was born into an environment I had no say in building, and I find it incompatible with my way of life (imagine being a white boy from the south on a plantation and against slavery, then shoved into the Civil war), I am, by definition now oppressed -- I am forced to be subservient to a system I had no say in building. I brought this up not to argue it but as a counter example to the person who just says "I am fine just living my life"
