I just watched an episode of Lou Grant (70's newspaper drama starring "Red" Ed Asner for the uninitiated). Immigration was the central plot theme. As you'd expect, it was a sympathetic treatment, but reasonably balanced pro and con.
It's noteworthy because the only things significantly different then to now were the clothes and cars. As I listened to the dialogue, it could have been right out of a current news story or a discussion here.
Frustrating and depressing.
