Have the entire healthcare system gov run. Need funds for it? Write em up out of thin air. Keep wages pegged above avg labor market because having a healthy society is more productive than an unhealthy one. To the extent where all other industries come 2nd as they are basically useless without healthcare keeping their workforce alive. Can't run a company if all your workers can't get well once they get sick. Literal unnecessary waste of human resources all because we want to prop up a few folks profits? The jobs and demand for the work will still be there if it's gov run, you just don't have a swathe of investors profiting off it. Zero loss. Go invest elsewhere.
One of the arguments against this is inflation from creating money out of thin air to fund it. Its a lie. The service is required and you don't get inflation from paying folks a wage to do a job. You do get it by propping up profits of private companies which essentually through the fattening of their bank accounts devalues money. Remember if you have a large number of folks competing for a good or service and they are all on similar playing fields (e.g wages near market avg), competition is high, the value of each dollar earned remains high.
If you have a handful of companies with buying power that far outweighs that of others allowing them to capture more than their share of a service or good because they can literally just throw more money at it than the majority of us can. This drives Inflation. It devalues money creating a new norm of your dollars being worth less.
Tldr: The benefit from entirely gov funded healthcare far outweighs that of a privatized system.
