M4A is very popular, with 69% support in the US. The reason it hasn’t been instituted is that the US is an oligarchy. As such, policy is formed according to the desires of the oligarchic class rather than broad public opinion, and they oppose M4A. Regarding voters, an aside I find pretty rich is that among those 65 years and older, i.e., voters who currently enjoy Medicare coverage, and overwhelmingly regard the program positively, support for M4A is only 46%.
