It's short-sighted nonsense that undocumented immigrants can't get SSNs. They should be issued SSNs and pay taxes as usual. They are working, and the IRS should be collecting taxes, nothing more, nothing less. If they aren't paying taxes, someone else has to make up the difference.
Likewise I want them to get licenses if they can pass the driving laws test, and should be able to get insurance. I don't want to be hit (or hit and run) by an uninsured driver.
They and their kids should be getting the same vaccines someone with a legal right to live here does, under the same terms. This is basic public health that helps everybody.
This is 100% orthogonal to whether ICE should be pursuing and deporting this or that person. They current system makes the rest of us less safe -- and that's not even getting into the massive impingement on the human rights of law abiding folks due to the misincented immigration (and other) laws and their enforcement).
