I don’t think this is true. It’s not that Obama and Democrats want premiums and deductibles to be high. It’s simply enough that Congress has refused to implement price controls. The only possible solutions to lower prices are really quite simple:
Regulate the prices federally and give all US citizens access to national private (regulated) plans.
Allow insurers to sell nationally and have an “open market” and hope market “forces” and competition will bring down the price.
Democrats have wanted to do 1 (or a single-payer Medicaid option for all) but have not had the votes in Congress to implement it since the ACA was passed. Thus, insurance companies have raised the prices consistently each year until they are just too high for most people to afford. Republicans have wanted to take option 2, and now they can! We’ll all get to see whether it’s true that “market forces and competition will lower the cost of healthcare.”
For my money, I don’t believe it will. Partially because it’s unlikely that a Trump administration and a Republican congress will be interested in enforcing antitrust suits against insurance companies. I expect a repeal of the ACA (partial), an “open, cross-border market,” and prices to increase over the next five years. We’ll hear lots about how it’s due to the price of research (bullshit), the expense of covering poor and sick people (partially true), and probably due to the Democrats anyways (bullshit).
But, maybe it will work and we’ll all save money and have cheap insulin! Personally, I strongly suspect that Donald Trump does not give two thoughts in his entire life to sick, the poor, or diabetics. I just don’t think anyone is going to care about the price of insulin other than diabetics.
