Cut off benefits (and no crying because boo-hoo they are sick and cannot get health care), fine businesses that hire them to dry up a big reason that they come here, and no more everything in Spanish (or Mandarin, Cantonese, Vietnamese, Korean, et al) as well as in English. The biggest thing is to dry up the labor market. If cheap Americans wouldn't hire them, they wouldn't be here.
IMHO, this has great merit. Eliminate the incentives.
Due to the fact that advanced middle age has come upon me hand in hand with accelerated decrepitude, I get to "enjoy" more than my fair share of visits to various hospitals. (I'm nearly to the point that I can call out the serial number of an MRI machine after ten seconds of listening to the "whammawhammawhammaWHUMP" sounds it makes:)
Anyway, one of the hospitals I grace with truckloads of Blue Cross Bucks has a phone hanging on the wall, visible from the registration cubical.
It is the strangest phone I have ever seen in my life.
I finally broke down and asked what's the deal with that phone?
Turns out that the hospital is required to be able to provide translation to/from any language imaginable. So, when someone comes in, speaking some strange dialect of Lower Slobovian, they get on that phone, and in a few minutes, they're talking with a translator.
I can only imagine the cost of that kind of "service". It's made even more absurd that in the rural area I'm in, I would be extremely surprised if they ever encounter a patient who did not speak either English or Spanish (with the latter becoming of course an increasingly large percentage). BTW, it seemed to me like a lot of the people working at the hospital were bilingual. (I know that the person I was speaking with was, because she works as a translator for the school where my wife teaches.)
Seems like "we" are committed to chasing after every imaginable "service", no matter how marginal the "benefit", no matter how expensive the COST.
Yet, things that really do matter are not given the time of day.
We are not only dedicated to rearanging the deck chairs on the Titanic, but, we've apparently committed ourself to "repurposing" every crew member to that "task". People are called away from the lifeboats, in order to fart around with the deck chairs.
There is a word for that kind of stuff. The word is "madness".
