This is not a comment to be pro illegal immigrant and storm our borders, but the adverse reply was that immigrants awaiting temp/perm residency overburden our medical services. In the year 2015 - 2017, US citizens totaled over $42M in uncompensated costs. Who pays that costs, you and me who carry insurance.
On reversal, while we also pay for undocumented immigrants medical care they contribute a F ton to our economy:
Taxes: In 2022, undocumented immigrants paid $96.7 billion in federal, state, and local taxes. This included $59.4 billion to the federal government and $37.3 billion to states and localities.
The main takeaway is, this country needs some sorta path to citizenship. Undocumented immigrants don't just take resources, but give back. There just needs to be a better process.
