No. I can tell you that's not how pharma works or capital markets in general. Rich people don't fund pharma research. It's regular working people. Teachers, firemen, truck drivers, nurses, and everyday working people. Via their union dues, pension funds, 401k's, college saving plans, savings, mortgages, life insurance. Every 2-4 weeks, they get a chunk of money taken from their paychecks for which they have no idea what happens to it, other than it somehow magically grows.
And what's with the wealthy fetish? I can also unequivocally say I've worked in the past with, and for, more 7 and 8 figure earners than you. They aren't going to be buying Gwyneth Paltrow vagina candles, but their wives, kids, and mistresses will use their money to pay for a ton of nonsense. Then again, you'd probably consider these people "nouveau riche" as they work for a living.
