It clearly IS the remedy, and not only doable; but also on display in Europe's Central Democracies... along with Canada.
What stands in the way are those who profit FROM the dis-ease.
The entire medical model, however, has been too largely captured by Big Pharma and too many "cures" come down to expensive treatment programs that MAINTAIN the disorder...
Like the War on Terror, there's more money to be made from MAINTAINING conflicts than resolving them. This mentality extends to modern medicine... companies that produce Asthma inhalers or Diabetes medications prefer to have a reliable "client base" through which to project future sales and quarterly stock dividends.
The for-profit, one-size-fits-all medical management paradigm is very unhealthy on so many levels.
And I didn't even get to the matter of how much chemical overload and overall toxicity impact our food, air, soil, and water and what this onslaught means to the very premise of well-being (or health)!
In short, it's a mess. However, so long as the 1% profit holders wish to maintain their stranglehold over working families, they will hold out piecemeal "solutions" instead of the whole enchilada. That's one of the primary reasons why Sanders was kept out of the spotlight, misrepresented, and his voting count numbers totally tallied with.
Insurance is one of the major corporate players in the U.S. duopoly. The merchants of that legalized form of graft are not about to lose the kind of $ made from keeping people sick and treating their medical programs like a sophisticated game of LOTTO where a select few win the "prize" of excellent treatment and many others go without... or otherwise, receive minimal care.
