You get both, Facebook’s job is to be known about, so you know about it. There’s a ton of companies doing drug research basically silently… in the US. Most fail, it doesn’t matter as long as a few succeed.
It's worth pointing out that the biggest innovations (both scientifically, but likely also monetary) in the biomedical field in the last years happened in Europe not the US. So that seems to disprove the point that innovation happens in the US because of the chance of going from 100k to 100M.
The reality is that you get crap like Facebook, Instagram, Xwitter.
