Someone has to buy the lab equipment and pay the scientists. If you think their profit is 'exorbitant', then you should be investing in pharma. But historically and as a whole, they generate returns comparable to the rest of industry.
You make a good point here. I think the article should have discussed this a bit, I made the assumption that they were cavalierly trying to copy drugs currently under patent. If that is not the case, I mostly retract my criticism of them. Thanks for pointing this out.
