He wouldn't have to make up an answer. The answer is that it would. Plus, it costs millions upon millions of dollars to develop, test and market a drug. Most do not even make it to the final phase. I believe that it takes an average of 14 years for the ones that do make it to market.
To add, many companies have to defend themselves against lawsuits, many of which are unfounded. So, that is very expensive.
The cancer drugs are nothing short of a miracle. They are expensive, but they work. The anemia drugs to counter the chemo side effects work, too. All of the drug companies will give free drugs to those who are truly in need. My sister was able to get all of her medicine for free. I, who had insurance coverage, paid thousands a month in copay. I consider it well worth it, though.
