A few clarifications:

-the treatment (may or may not be a drug) would only work on people who had (or were very close to having) bipolar. Kind of like how antidepressants often can make us manic, but few non-bipolar individuals have this side effect. So, unfortunately there still would be "losers", because of the treatment was used on people who had never been hypo, it would be enhancement. It also would be considerably more difficult to develop, since it would have to work on 2 sets of people with very different mood experiences.

- Brave New World is one of my favorite books, along with Fahrenheit 451 and 1984. Rest assured that the treatment would be nothing like soma! It would not keep us in a fake, stupid happy state, but rather would give us prolonged mental clarity and the energy to take action when action needs to be taken. Soma was used to deny the massed of their liberty; this treatment would liberate us, both from anyone who claims too much authority over us, and from the cycling which has enchained us.
