I lived in the US for 6 years, and worked at above average tech company and had excellent healthcare benefits through employer. I must admit it blinds people to say "country's messed up healthcare system is not my problem" because my employer took care of it :-(
Before my move to Europe, I risked living in the US for a month without health Insurance, and I was very anxious about it. I can't imagine what most Americans who don't have that luxury of employer benefits feel daily.
It's silly to think that the richest country on earth by far does not have a decent healthcare system that covers all of its citizens.
This is something I never understood. If your employer is in power of your health insurance, how free are you?

To your point, the affordable health care act addressed the issue with not being able to get insurance due to preexisting conditions. In the US you're required to have healthcare insurance. You can buy it yourself, get it through your employer, or, assuming you qualify, get it from the government.
Also you're not required to have insurance. The individual mandate was repealed a couple of years ago.
I don't know the particulars of what law enabled this, but I used my dad's health insurance until I was 26 as well, before Obama's first term.
I got my first "real" job after spending a year trying to find a full time job after graduating college, during which I was working that 12/hr job. Even at the new job which paid 80k a year, I had to pay $30/paycheck ($60/mo) towards healthcare. Thankfully never had to use that insurance while I worked there.
Now at my current place I get HDHP (high deductible health plan) and when I messed up my leg the hospital I went to didn't even have crutches in their inventory.. got wheeled out to my car and I had to drive to a pharmacy to purchase crutches.. it was horrible, and I couldn't imagine what this situation must be like for someone without insurance.
Anyway the worst part is that I still ended up paying about $1500 out of pocket, because the 1st X-Ray was covered, but the next two were $600 each....... $40 crutches ..............
