Socialize medicine is not Democracy but Socialism, making it a threat to Democracy. The easiest way to know threats to Democracy is to ask if this is Socialism or Democratic. Free market is closer to Democracy. More choices are more Democratic.
Once Government controls medicine, there will be less services and higher prices. This is not bad, if you are a parasite, since there is no change in cost to you but you still get something for nothing. But someone who has to suddenly pay more for less will not be happy. For one thing, there will be less R&D for future medicines and procedures, since this costs money, has risk and there is no guarantee. Future medicine takes the free market entrepreneurial spirit, to take a risk, with the hope of finding the treasure. Bureaucrats will not take that risk for you, since they serve themselves. No middle or upper level manager will put his career on the line, if he wish to advance in the system. Everything slows down to avoid risk. What we have today, in medicine, will be it; stalled in time.
Government makes it hard to fire anyone, and therefore with a medicine monopoly and total job security, nobody needs to hustle or think in terms of pricing, quality and customer service. I remember my first government contractor job; DOE, and wanting to work fast and being approached to slow down, since I was making the status quo look bad. It was either be black balled; uncooperative technicians, or learn to pace myself and not make waves. This slow down leads to rationing and long lines, since hustling needed for good service is taboo.
If you expect something for nothing, anything is an update, compared to nothing. But if you are used to customers service and better pricing and quality as the way for a competitive market to stay ahead of the competition, you are in for a surprise; night mare.
I am hoping when Trump gets in, he can improve the government job philosophy and efficiency. If the Government had the proper free market attitude, it may actually work. But it will be a disaster, as the Government currently stands; lazy and self serving foot dragging with added red tape, to justify too many union people to ever do the job in a cost effective and innovative way.
