The thing about having the government pay for healthcare at the national level is that it would also incentivize prevention of diseases, as a way to cut costs over the long term. At least that's what's supposed to happen without too strong Big Pharma lobbying that would prefer the population to be as sick as possible.
How does that happen? Doesn't this imply government interference in people's lives (eat this, eat that, exercise etc.,)? Given that such advice is frequently shown to be wrong, this is problematic.
The NHS doesn't seem to incentivize prevention of diabetes in the UK. To quote 'UK Diabetes': "Diabetes is the fastest growing health threat of our times and an urgent public health issue. Since 1996, the number of people living with diabetes has more than doubled. If nothing changes, it is estimated that over five million people in the UK will have diabetes.". This disease largely results from personal choices often made on the basis of misleading information.
Just keep in mind that we will likely never reach the ideal balance between the voice of the people and megaphone of money.
The impact of lobbyists and money is a necessary consideration in any discussion of political solutions to problems.
