That Kennedy immigration bill of 1965 is a big negative but does the added on “chain migration” add a lot to it? That might be the worse culprit here. 70% of legal immigration is the chain migration, immigration per year might be something like 1.3 million.
Pity, US landed on the moon, fought World War II and 275 years after our country’s birth, people will mainly be voting along racial lines. Nightmare.
