I simply don't understand the healthcare system in the US. Its meant to be a free market, yet insulin costs a ridiculous amount. However Opioids and synthetic opioids are cheap as chips.

To put it into context, In the UK the NHS buy Insulin at <$35

you can see the prices here: https://bnf.nice.org.uk/medicinal-forms/insulin.html They come from the same companies and are produced to the same standard. How can a bureaucratic "socialist" care system get better price, and a much better availability than a "free market" system. (thats rhetorical, I know why)

Given the number of non and under insured, I just don't understand why its not swinging elections.
