Sorry, I'm not going to read huffpo drivel. Link to something more credible. Regardless of where/how the money is spent, the reality is that the money is spent creating, developing, testing and producing the drugs.
So making billions every year is not enough?
First, who's definition of "enough" are you going to use? Isn't $40k per year enough for anyone to live from? Why does anyone need more?
Second, if you need $100 billion in capital to make $1 billion in profit, then no, it's not enough because investors will put that $100 billion to other more productive use.
Look, cast aside the utopian drivel for a second. We're seeing this play out right now with antibiotics and vaccines. The monetary incentives for creating new antibiotics or producing vaccines isn't there anymore, and lo and behold, we're not getting a lot of newer more effective antibiotics.
It's all about the incentives.
