Healthcare is pretty simple.
Everyone wants somebody else to pay for their excellent healthcare.
When somebody else is paying, they pay little attention to the costs.
As long as 3rd parties are mandated to cover costs, Hospitals/MDs can pretty much charge what they want. When you are sick, you do not usually care about the bill until it arrives. Hard to shop around for price. Some providers even offer payment plans for those short on cash.
Few will price shop before authorizing an ambulance ride to the hospital with a heart attack. They bill therfore is often jaw dropping.
If every provider was forced to list their services prices, then we could shop around. There are already services that rate hospitals on the quality of their care.
Most everybody in US has access to emergency medical care. Poor get it at emergency rooms, rich get it from their family doctors, workers get it through their employee, some pay privately for their coverage, and rarely is that a patient pays the bill as they leave the Dr. office or hospital. Even some pharmacies have walk in urgent care mini-clinics. Get a flu shot, prescription, blood pressure check, pick some insulin, a pack of needles, or even a few stitches or band aid.
There are also tons of pay for service providers that don't get covered by insurance. Lasix, Plastic Surgery, eyeglasses, hearing aids, tattoo parlors, hair implants, accupuncture, massage, skin resurfacing, laser, ciropractic, exercise, yoga, the options seem to be endless.
I even get solicited by a local lab test company to get customer pay medical blood and urine testing.
Healthcare seems to be readily available for most.
Many still fall through the cracks. I believe the current biggest issue is getting healthcare to the people on the streets. There are also hundreds of thousands of people from other countries that sneak into this country with no medical clearance, documentation and no jobs. Their are some free clinics opening near the encampments, but they have challenges to garner funding.
Except for a few, very wealthy (usually oil money) socialist countries, most that offer free healthcare revert to throttling to keep costs under control. Many die waiting for services, and many services are not offered at all.
