Instead of focusing on how to pay for healthcare I prefer to look at how to decrease the amount that has to be paid..
Everyone has to have it just like water, sewer, electricity, etc., so let's regulate like other necessities, i.e. utilities.
Clinics, physicians, pharmacies, hospitals, labs will be able charge enough to make a good profit.
And yet not an outrageous profit.
If their costs go up they can request price increases.
If costs go down, the prices go down.
Insurance companies get same considerations.
Their premiums will be tied to expenditures.
Providers will be required to help fund services in rural, undeserved areas to insure everyone has care.
There will be a public commission to do the regulating.
Transparency! Don't we all like transparency?
There will be a system of incentives to encourage preventive care, public health education, and for introducing efficiencies into the healthcare system that improve care and/or lower costs.
