Unaccompanied children come to our border every day, so this isn't different than what happened under Trump or Obama.
Are we to assume now with Trump out of office and Biden in, thousands of migrants in "overflow facilities" (not camps or detention centers) will be treated like royalty in facilities similar to a 4 star hotel?
Does anyone ever ask whether any country in the world has the infrastructure/ finances/ staffing to bring in thousands of migrants on a daily basis? What would Canada do if 10,000 American migrants showed up at the border requesting shelter, food, clothing, and healthcare?
Open border + welfare state = collapse.
All that is before we get to the Covid issue which is another wild card thrown in the mix here.
