Whatever, believe what you want. If regulations are needed to bring prices down, then you can't claim market demand is working like it should.
There is no shortage of drugs in this country; if supply and demand were at play, then prices would drop, but they don't. Prices are artificially kept high for Americans because they can, because of greed, because of politics. You are on your deathbed, and the only option is to pay what they say to pay. We can't shop for the best deal because there are none. That's not market demand, that's a mob boss holding a gun to your head.
