First we need to make a very important distinction...What most people are referring to as "insurance" boils down to pre-paid medical...There's a world of difference....This is why the auto insurance analogy doesn't fly....If your auto insurance worked the same way that people are expecting medical "insurance" to work, it would cover new tires, oil changes, new paint jobs, etcetera.Oddball, the more people being insured, the more jobs in the insurance industry....many of the 30 million extra being insured will probably get their annual physicals and tests, those will lead to early treatments and more tests and doctor visits, saving peoples lives or extending them, people already with insurance will have measures in their insurance that limits out of pocket expenses or additional costs on things like physicals, mammograms, colonoscopes...this all can lead to early detection and more treatments and tests.
The supply for all of the increased numbers in people using our health care system is bound to rise, which means ''demand'' will no doubt, go up and it will be met with the appropriate ''supply'' in doctors, nurses, clerks, professors, lab techs, hospitals, medical schools etc...
That's just how ''the market'' works....
Will we have shortages of workers to serve demand in the beginning? Most certainly! But the ''market'' will adjust and will give us the ''supply'' needed....
This is going to put a massive burden on the system, with the person receiving the service completely insulated from from any concern of whether they're over-utilizing the system, because there's no cost disincentive to do so.
Meanwhile, reimbursements are going to drop like a rock (checked the Medicare reimbursement rates lately?), because there's not going to be enough funding to go around...So you'll end up with rationing at both ends of the transaction.
Now, who in their right mind is going to want to work in an environment like that?
