Regardless if someone agrees or disagrees with Alexandria Ocasio-Cortez, her election was the result of an unresolved issue: That issue is healthcare. Regardless of the other platforms she ran on, chances are she was elected because of her stance on Medicare for all.
So far neither party has offered a realistic solution to the healthcare problem. The Affordable Care Act forced people to buy a product, which is not a long term solution. The simple truth is, the government can not afford to subsidize out of control healthcare costs.
To fix the healthcare problem we have to take it down to the root problem: There are not enough doctors. This is simple supply and demand. The fewer doctors we have, the higher the cost. If medical schools were to open the flood gates and make more doctors, prices would go down. As it stands, most of rural America has to drive 100+ miles to find a specialist in certain fields.
