Let me give you a very serious, economic answer.
1. "free" services to illegals are allocated by a massively long queue.
2. The good is allocated based upon highest endangering need whereby that individual can still live while waiting for treatment.
3. Queing becomes ever more problematic as the Hospital then has to seek funds from Foundations, Charities and Federal and State reimbursement.
4. The market system then is completely broken.
Ok. Now. Glance up and think. where have you heard this description before???????
Go back to the food lines in the Communistic Russia and compare the similarities.
The essences of a non-market allocation model distributing goods and services by a non-market mechanism creates massive queues, very poor quality of services and shoddy goods.
How is that any different than today's Federal Medical Insurance solution? How is it any different than the disappearance of any new investment into the system to streamline insurance, medicine, or fundamental care for the illegals?
What this tells me that the USA has unwittingly embraced a Communistic system for delivering healthcare in the inner cities while trying to hold onto a market system for the outlying areas.
This medical insurance bill completely muddies that water of separation and will steal resources from the healthy market portions of that system and try to use them as additional sources to defray the queing and non-market delivery of goods and services.
To which answers the your question.
By beggering thy neighbor, the social engineers will try to enlarge their communistic system.
