The election of Obama showed that we had been doing the same thing as Europe (granted, with a mainly non-Muslim population) by bringing in masses of people in this country to replace the children we won’t bear. It also showed that we’d been doing it almost as long as France had, and that many of those people were not here to assimilate/lead productive lives.
You are absolutely correct. We are once again following Europe’s mistakes.
We need to close up our borders, throttle all immigration (legal and illegal), and not open the doors of immigration so long as immigrants in this country will not assimilate.
We also need to completely ditch socialism and Keynesian economics and get people back to supporting themselves.
