Seeing that pharmaceutical companies, on average, spend much more on marketing than R&D I would eliminate marketing.
Most of the rest of the world has banned drug advertisements, and sales reps whose activities more resemble bribery than anything else, and they're doing fine.
Don't even eliminate it. Just halve it. The typical drug "researcher" spends $2 on commercials and sports sponsorships for every $1 spent on R&D.
In addition to marketing, pharmaceutical companies spend, again on average, MUCH MUCH WAAAAAAAAY more on stock buybacks and dividends than they do R&D. Between $2 and $4 for every $1 spent on R&D.
That could also be a source of, oh who the hell am I kidding...
Modern drugmakers aren't biotechnology companies, they are financial instruments that just so happen, by coincidence, to employ chemists.
