For a new drug:
1) Discovery process: 4-8 years.
2) Clinical trials: 4- 7 years
3) FDA approval: 2-3 years
It averages out to about 15 years and tens of millions of dollars from conception to launch. Hundreds of employees will be working for years at a project that is losing money. Finally after approval the company will need to figure out how to make all of that money back and hopefully make a profit as well. They don't have much time to do it before their fruits of their labor are given away to other companies to be sold as generics. Then consider the money that is lost in trying to create new meds the the feds never approve. Finally we have thousands of lawyers out there digging for ANY reason to sue a drug manufacturer or doctor. Even after the FDA has studied and confirmed that a med is safe, the pharma company is on the hook for any adverse affect. If the drug saves the lives of a million people and 50 get sick from it, the lawyers go for blood. The cost is huge and is passed on to you.
The common belief is that there are 10 to 20 million illegal aliens in the U.S. Who get "free" medical care. Well it's not really free. The government does not pay for it. Hospitals do not pay for it. Insurance companies do not pay for it either. Who does? You do. Your insurance premiums, fees and other bills must cover the cost of providing medical care for someone who's legal address is in Mexico city. And worse, they don't even bother to thank you for taking care of them.
When the government takes over how screwed will you be? Obama claimed that after Obama care was implemented, that your medical care would get cheaper. Obama care has been partially implemented already and my costs have only gotten higher. What about yours? Can you think of anything that has gotten cheaper and more efficient after government has taken over? Yeah, neither can I. We are in the process of totally destroying the best health care system in the world.
