While I agree with you on facts 1,3, and 4 I think in regards to fact two the reality is due to increases in technology combined with the US being the best economy (still) in the world, I’m not sure there’s much Congress could do to legislate immigration.

The treacherous paths a decade ago that few immigrants would traverse across Central America and Mexico are now so easily accessible and traveled that multitudes of immigrants come in through the Southern border declaring asylum.

While visa overstays still constitute a part of the illegal immigrant population, it is less of a percentage than when it was the majority over a decade ago.

The reality is we will always be a magnet for immigrants because the overwhelming majority of them want to work hard so it’s an issue that doesn’t have an easy legislative fix. I would greatly favor an expansionist policy increasing guest worker visas, making TPS permanent for several countries (Ukraine, Afghanistan, Haiti, Samoa, etc.) but that can never reach the support it needs because no matter how many resources you allocate toward border enforcement it will never be enough for immigration restrictionists among both democrats and republicans.
