For people in the US, do you think we get overcharged for medicine?

So I saw this (see below) and wondered about the questions it posed.

My opinion: Obviously, some medicines are more expensive because that money gets put back into making and improving new drugs, however a lot of the time it also lines the pockets of huge corporations in the US. And we know this because medicine in other countries is nowhere near the price it is in the US. And even medical procedures are vastly overcharged for. (My dad literally paid a $500 copay yesterday for two stitches. Those stitches probably cost like 10 cents to make).
