The major improvement in the past six years is that another 15% of the population now has health insurance.
Which could have been addressed with perhaps 3 to 4 pages of legislation. Instead, we were force fed a 2000+ page monstrosity of regulation, after regulation, after regulation, after regulation, after mandate, after mandate, after mandate, after mandate, breaking every promise of keeping your doctor, keeping your insurance, and lowering healthcare costs, and instead has exponentially screwed the quality of that care being provided, that I've been privvy to, while the cost & premiums skyrocket. But yea, a few more people have that crappy Government mandated healthcare now, than before
