In order to increase or sustain the healthcare system, I also would argue, because it I propose a more immediate fix. Comprehensive immigration. There is no spending involved on the part of the government and it injects immediate income into the system from the taxes being infused by these persons, who as per present laws are not able to immediately draw from the coffers of the health system. The undocumented workers are already supporting the financial system. Government may choose to impose or increase fair taxes of those that take advantage of the new immigration status if they choose to punish those persons as law breakers or better yet, increase remittance fees for those sending currency back to their homelands. This increased remittance fees would add more money into the present economy and it also allows the US more elbow room from having to send actual tax dollars to those economies to prop them up, since those persons would be able to send such dollars there themselves.
This proposal thereby kills two birds with one stone as it were. It would build up the healthcare system thereby forwarding the medical benefits for US citizens and it would offset foreign aid spending to poorer countries. Legalizing these people also helps stave off long term migrant waves because increased income into the foreign homelands stabilizes those economies. and the added income injected into the US economy would solve the needed cash flow crisis being currently belly-ached about.
