What are you talking about? Non-citizen immigrants pay the exact same taxes as citizens. Not just "some" taxes.

Taxation is based on where you live, not your citizenships. (Well except US citizens who have to pay federal taxes even if they live abroad but that's an exception).

I was mostly thinking that poorly paid agricultural workers or other people doing periodic manual labor may be getting paid in cash, and perhaps they are not paying taxes on the money, even if they are legally required to. The wait staff and bartenders I used to know did not pay tax on their cash tips.

So what I am talking about is not what the legal requirement is, but to what degree it is followed. But to the degree these people pay taxes while here they are not getting a completely free ride when they take advantage of our tax-supported services.

On a related note, I would be happy for illegal immigrants to get at least some medical support, such as vaccinations and treatment for communicable diseases, as that benefits everybody.
