You are absolutely correct. American workers have been complaining of these exact same things since at least the 1830s.
If only we had listened.
DAMN those Irish!
It's not quite the same, in the 1830's we had a continent to expand into, today we are looking at being compressed into maybe 60% of that same continent.
Also, apart from some embarrassing moments during the mexican-American shoot ups, the Irish, Italians, Germans, etc. came here to become part of the nation and not to haul their old one into my backyard.
