The Aging Effect on Healthcare
Of course, Obamacare did not make anything really "free" except annual doctor visits. People on this board have repeatedly complained about higher than expected premiums and big deductibles.
I suspect that payment rates, which also preceded the ACA, played role in accelerating some retirements. The ACA likely had some impact, too. However, the rate of retirements has slowed in recent years, so it's still too soon to really glean what impact ACA had and what impact other factors e.g., aging of physicians had. I'm sure this will be a topic of future research, especially if physician shortages grow worse than expected.
A Canadian conservative is one who believes in limited government and that the government should stay out of our wallets and out of our bedrooms.
