The solution to diversity was to build up other countries where they were and not allow them to use the US as a release valve for their problems.
Even their research is deeply flawed, demonstrating that they don't even know how to conduct studies that aren't flawed by bias.
It reminds one of Jonathan Gruber of MIT who designed Obamacare. He had no experience in healthcare. He just dreamed up this great idea (says he) and insisted it would work.
Once again, another ridiculous idea of the Left has collapsed into a pile of burnt-out cinders.
Just what the hell does that mean???
