What are some theoretical solutions that would lead to win-win situations for everyone in the purple pill debate - every pill?

I say theoretical as in solutions that are physically impossible or too large-scale/long-term to implement with today's technology/laws/whatever, but could easily be imagined. For instance, causing everyone to lose their desire for sex and relationships & have reproduction be possible without sex, so that there would be no bitching about sex and relationships in the first place. Of course, that's a really shitty example but just so you can get the gist of the question. Another example would be if men and women were socialized the exact same way.

Thoughts?

Edit: Just want to add a really good example suggested by some of you: sentient human-shaped robots personalized for every human. It's quite interesting to think about considering that no human would be harmed as a result, no matter how otherwise cruel or disturbing the personalizations could be (especially for the most fucked up humans out there).
