I don't see any way to fix that under the law. The easiest way to get around that problem is to eliminate medical insurance entirely and just have people pay their doctors and pharmacists directly.
The anti-trust and anti-price-gouging laws are already on the books and in the US Code. What is needed is for the administration to have a spine and enforce these laws. Its time to put America First and to make America great again. Why should America always have to pay outrageous prices on medicines and health care products that most of the rest of the developed world gets at much lower prices?
