fundamentally socialized medicine and insurance do the same thing. if you argue that the current system is broken and that socialized medicine is the solution you're essentially just saying that the broken system will magically start working if different rich people without your best interests at heart were suddenly given control of the system. oh, and if everyone was forced to participate against their will if they worked, but even the people who did not work would still have their health looked after. this would potentially incentivize people into not working since one of their primary motivators -- the ability to look after their own health and wellbeing -- has been removed and replaced by the state. oh, also, the people who you put in charge are the same ones who were already in charge. after all, you've been complaining about how the reason the system is broken is because of health and insurance executives being tangled up with the government by way of lobbying or even more direct methods. do you think those people just disappeared when you suddenly gave total control to the government? because they are still there and they still just want to make as much money out of you as possible.
You seem to be treating this as a purely hypothetical scenario when in fact multiple countries have been operating this way for years. ---
