I'm from a country where the government has several institutions to provide healthcare. It's not the absolute best, and depending on the institution one qualifies for it might not be quickest or cover all conditions.
As administrations have come and gone, there's been a back and forth between officials who want to privatize health, claiming inefficiency, dilapidated facilities and that the system is a drag on public finances, and officials who want to save the system from what they claim is purposeful gross mismanagement by administrations who want excuses to privatize it.
Overall, even if not as pristine or efficient as the private sector, this system of healthcare does means the private industry has to compete with "free".
When I have a cold, I don't think I've spent more than $10-20 on a private doctor's appointment, out of pocket with no insurance. I had a rare eye condition called Keratoconus. In the USA, the specialized procedure to treat it seems to generally cost between $2,500 and $4,000 per eye [1]. I paid about $650 per eye on a private ophthalmology clinic, again, with no insurance.
EDIT: To add an addendum, and in the topic of "efficiency", whenever I'm back home I tend to have more face-to-face time with my doctor. There isn't a team of nurses on every clinic to talk to and do the menial work. I even book appointments directly via WhatsApp with my gastroenterologist, and transfer money directly to their bank account, instead of going through a front-desk secretary, forms, and apps/paperwork. Without insurance "networks" I hear of a good doctor and just go, no problem.
This also means I tend to go to the doctor when I'm home, rather than when I'm in the USA. I find very interesting how for me personally, the experience seems to be much better in a country with an overall lower purchasing power than the USA.
Or, if the government was doing an awesome job, the private sector might want to get rid of public sector price ceilings.
The private tax prep lobby wants to keep the government out of tax filing.
Logistics companies want to kill the USPS.
