@ehBeth,
I have considered all of the points raised and they don't provide me with an answer.
Obamacare is here to stay. The point at which something could have been done to reverse or seriously modify it has been passed, and so the utility of reaching conclusions, based on speculation and projection, about the existing question is greatly diminshed.
I've no doubt that there are many young people who are motivated to become doctors for reasons other than wealth and that all medical students have not enrolled to become "rich."
The question (at least for me) is whether or not the time and money needed to obtain a medical education will disuade a significant number of young people from acting on their high minded intent if it appears to them that they can't make an income that will attend to their large debt in a relatively short period of time and leave them satisfactorily compensated.
Presently no one can answer that question, and if there is something that can be done about it (e.g. federally subsidized medical tuition) it's not likely to seriously be considered until we have an answer.
If you would like, I will acknowledge that the points raised could prove out and a shortage of doctors will not be a problem, but that is only one of the potential problems Obamacare may deliver.
If Obamacare turns out to be the Godsend so many people expect it to be, I would be foolish to insist it's not, and happy it turned out to be a big government program that works.
I just don't think we will all be judging it's ultimate performance based on the same set of criteria.
Whether or not it (or any other entitlement program for that matter) eventually results in an economic crisis the likes of which we now see in Western Europe will, for me at least, be an indication of failure.
I'm not hoping for this as I don't place an ability to say "I told you so." over the well being of my family friends and fellow Americans, but I believe I have legitimate reasons to be less sanguine than some in this thread.
That a majority of Americans chose Barrack Obama to be our president for the next four years means his second term is legitimate and just. It doesn't mean that all of my fears were groundless, that it was the right decision, and that his second term will be a success.
We will just have to wait and see.
