Corporate greed doesn't care who picks it, as long as they are cheap labor and they profit from it. If national sovereignty is damaged or destroyed as a direct result, they could care less! Bring them the bushels of bucks and keep that cheap labor coming.
Once today's illegals are "guest workered" or become citizens, they'll demand equal pay for their hard work. Once the "guest workers" or "new citizens" are then laid off, who will employ them? It appears history will be repeating itself - we are breeding our next welfare state no thanks to executives whose "bottom lines" are more important than national security or national sovereignty.
