There will always be a night/weekend differential. There will always be those who are willing to work 40 hours fo $X per week and those who work 60 hours for $1.5X per week.
If it comes to it and things get really bad, there are plenty of members of generation me who will get an attitude adjustment who will work what many consider "slave hours" today and lots of weekends if it means paying the mortgage, getting your kid braces, etc.
As usual Doze you are correct about the economics of work. If a CRNA won't do the job the AMC or CEO will find someone who will. Ditto for the MD (A).
While seeing into the future is very difficult the single payer system follows the public option. So, while the clock starts ticking this January with Obamacare the real clock is when President Clinton gets the public option added to the law in 2017.
I suspect after the public option is added circa January 2018 the demise of private insurance will take 3-5 years followed by a single payer system. Obama knew from the beginning his bill was a method to go from "here to there" with there being a single payer system.
The next thing we see as providers on the ground is more AMCs or Employed positions utilizing the collaborative model to save money for the hospital. I expect that to become more common in a few years.
The high paying existing groups with MD only providers are at risk under the new Obamacare paradigm. They can hold out as long as the hospital subsidy is low or zero and the public option isn't available. Once the public option is added these groups are toast. The Groups with the ACT can hold out if their subsidy is low or zero for a bit longer.
But, the majority of Groups in the USA, 50% or more, that receive a significant hospital subsidy are at risk of financial disaster under Obamacare unless they hire more CRNAs and move away from medical direction as Anesthesiologists retire or leave the Group.
With this kind of financial pressure down the road along with massive increase in rules and regulations many groups are selling out to AMCs. These AMCs then slash salaries and benefits for ALL anesthesia providers in order to maximize profits.
The end result of all this is that many Anesthesiologists see the end of private practice in 5-15 years. They are selling out or holding the line on expenses as the end game is clear.
New hires are faced with the dilemma of an employee model vs. a partnership track.
IMHO, nobody should take a partnership track without a clause for inclusion in the profits of the sale of the company after 12 months. That clause could be worth 1-2 million dollars.
