Yes the drug companies pay for the research and sell the drugs. Question is if Trump lowers drug prices who is going to help the drug companies recoup their money?
Funny story, in 1992 the government passed a law that banks needed to make a larger percent of their loans to pay for housing for the poor. We call these "subprime mortgages" meaning the people have poor credit. Well in 1994 the banks figured out they could do this by selling "mortgage swaps". The idea is that if you package a thousand of these mortgages together you reduce the risk to the investor of any one of them going bust. Then they created this pipeline where the banks could write the mortgage and then sell it to an investment bank which could then sell it to a pension fund. In this way the bank didn't need to worry about the loan going bust.
Well once the bank was no longer worried about the loan going bust they got very liberal on loan applications. They even wrote "no income no job approved" loans. They were doing this because of the new law. But they were not stupid, they knew the loans would go bust, so what they did was create balloon mortgages. Maybe you pay 2k a month for the first sixty months and then the mortgage doubles to 4k a month. At that point they can't pay, you foreclose, but only after you got 120k from the suckers.
Yep, that law in 1992 led to the Subprime mortgage crisis in 2008.
But don't worry, I know what you are thinking, what happens to those poor stock brokers on Wall Street when this goes bust? No problem, you see a study was done after 911 that fully exposed how the US government could have spotted the terrorists beforehand and would have spotted them had they not canceled a certain program at the NSA designed to do just that one year earlier. They knew enough about 911 and the governments involvement to guarantee that no one would go to prison. You think I must be joking, a crime this big, no doubt thousands went to jail. But no, they were right, it was the taxpayers who bailed them out and even paid those wall street brokers big fat bonuses.
