I guess you regret not investing in them...or perhaps that you didn't
have any money to invest in the first place.

I hope you had a good giggle reading Peterb & Roman Bystrianik's lie
about Pharma companies comprising over 90% of the fortune 500.
The pharma industry is a good business to be in, but it ranks around
4th, not 1st in most "metrics of return" (quoting Peterb).
Of course, many pharma companies make dietary supplements, band aids,
aspirin, isopropyl alcohol, etc.  Keep that in mind when you
think about their profits.  (They make and sell vitamins because its
very profitable for them to do so or they would just focus on the
pharma products)
