This article will make you wonder how much of the cost of so many things can be attributed to regulation.
Is it really worth it?
I think not.
Think about it.
The solution is to change regulations, not to have a free market (at least not free as in anarchy). The current regulations are the response to free markets on drugs in the early twentieth(?) and before which lead to heroin cough syrup and people dying from snake oil treatments. There needs to be regulation to ensure safety, and the regulations need to change when people exploit them.
Why not free market with opt-in safety agencies? Have it so people can sell/buy them freely if they know what's up, and distributors can pay to have safety checks on their products which is then shown to the consumer. Because as it stands, a lot of people just illegally buy the drugs from other countries where it's cheaper. Best of both worlds, really.
