Demand the US FDA make importing drugs from Canada safe

I read on the FDA web site various reports of how unsafe it is buy imported medications. Instead of merely warning people about dangers of using import drugs (Canadian-Mexican)I believe the FDA should make it safer for US citizens to have these drugs. I strongly suspect while admittedly there are safety factors, it's also eliminating competition for US Pharmaceuticals. Americans are charged the highest prices for prescriptions than anywhere else in the world. Canada and Mexico make identical drugs and charge at least half the price.
The FDA should do all they can to insure the safety of all imported drugs.
Imstead of warnings, why not change. IE Trying their best in insure quality,safety in prescription drugs.
