Universal healthcare is a potential solution, however, it is not panacea.
That is exactly what we are discussing – the fact that universal healthcare is a possible solution to our absolutely horrible current system. No one here is dumb enough to believe in any 'panacea'. There are downsides to everything.
One thing no one is discussing is how much the current system, in particular the meidcal insurance costs to businesses (especially small businesses), is a major drain on the resources/profits of these companies. Spiralling healthcare costs, especially of the retirees living on pensions, has severely stressed, and even bankrupt many a company's pension program.
This has resulted in the elimination of these programs by many companies for current and future employees.
