The bottom line is you can only have open borders if you’re willing to dismantle the welfare system. You can choose to have open borders with mexico but you can’t give a dime in any sort of benefits to those mexicans citizens that want to come here. That’s the only workable solution unless you’re going to run the race to the bottom where you equalize everybody in the middle and the bottom. Unfortunately the equilibrium of such a scenario means a significant quality of life degradation for the vast majority of the middle class here in America.
Why are there millions of “Refugees” entering Europe and attempting to get to Germany rather than stopping at the first point of entry (aka Greece or Hungary). The obvious answer is there’s a lot more free shit to be had if you wind up in Germany with nothing.
