Working men go where the good work is. America has fukked over everything south of the border, so people are going where they can to support their families. I noticed you cut out the part about capital having no borders.
That's because we are talking about illegal immigration, not capital. You are playing a game of whataboutism here.
Again, why do you support illegal immigration? In fact, what are the many reasons you support it since you said there can be a number of reasons to support it. And remember we are talking about ILLEGAL immigration, not legal immigration.
How that works is propaganda from white supremacists who fear an increasingly brown America. They are undocumented workers, this is true. I support giving them documents, just like good old Ellis Island.
If I went went to Canada and stayed illegally I would be an illegal immigrant. I immigrated to their country illegally. That's a definition, not white supremacy.
