Yes, yes, yes... very nice, I'm sure...:Yeah, we should never have allowed all those Catholics, Micks, Eyetalians, Pollocks, Frogs, Ruskies, Krauts, and other scum come here. YUGE mistake. They totally destroyed our culture and history!
The trouble with your analogy is that back then we were a nation of 70 - 100,000,000 million souls, with vast tracts of open land, and work for anyone who wanted it...
However, today, we are a nation of 330,000,000 souls, and all the land has been parceled out, and we cannot employ nor feed nor clothe our own without communal effort...
Things change...
I am glad that my ancestors managed to get here before we grew so crowded and became much pickier about whom we allow in and whom we do not...
But it is what it is...
We can no longer afford an open-door / open-borders policy just to make Lib-Progs feel good and to maintain an open-door policy that no longer works for the Republic...
Time for a 20 or 30 or 40 or 50 year -long moratorium on large-scale immigration...
We have all the souls we need ( One-Third of a BILLION nowadays ) and that's quite enough for the next generation or two, thank you very much.
If we can't figure it out on our own or manufacture it on our own or build it on our own or maintain it on our own or heal it on our own then we don't need it, in the long run.
Time to close the door and padlock it for a while.
