If healthcare were truly based on free market principles, there would be no need for individual mandates! Why? Because healthcare would be extremely affordable.
It would be like going to the grocery store to do some shopping. (You do not rely on an insurance company to negotiate prices with the food providers; you do not use an insurance plan to pay for all your grocery bills; you are not under the mercy of an insurance policy that will ration your food consumption patterns.)
The problem with both ObamaCare and RomneyCare is that they do nothing to increase the supply of doctors in the marketplace. Instead it merely increases the demand for doctors. This is a recipe for disastrous inflation of healthcare costs for the consumer.
And did you know the Rockefellers (during the early 20th century) were instrumental in limiting the supply of doctors and medical schools … which is contributing to the extremely high prices for healthcare today? That’s why we “need” insurance for routine care (and for catastrophic care, too).
