1. Bring about absolute gender and racial equality internationally.
2. Discourage homophobia and add homosexuality nonchalantly into films, literature and even fairy tales, so from an early age most people don't regard it as bad or unusual whatsoever.
3. Make child indoctrination illegal.
4. Introduce a "Parent's License", similar to a driver's license.
5. Convert prisons into rehabilitation clinics.
6. Disallow capital punishment.
7. There shouldn't be an age of consent for sex; the existence of this could pressurise young adults who reach that age into having sex when they're not ready. Instead, the age of consent can vary based on whether the person in question is physically, emotionally and mentally ready.
8. Abolish faith schools.
9. Imprison people with willful ignorance, but not those with circumstantial ignorance. I'll explain what I mean by this terms: somebody who is willfully ignorant has the health and resources to become more intelligent (e.g. celebrities, with much wealth and technology at their fingertips) but chooses not to, whereas someone who is circumstantially ignorant is someone who can't become more intelligent even if they want to (e.g. living in a poor country with no access to a library or computer) or someone who is unintelligent due to a mental illness.
Of course, many of us are wilfully ignorant in one way or another (all reading this has access to the Internet, so could learn about complex quantum physics but may choose not to), so I mean only extremely willfully ignorant people should be imprisoned. This means the cast of Jersey Shore, Rick Perry, Big Brother contestants, etc would be locked up.

10. Allow gay marriage internationally.
11. Replace holy books in schools with texts by Richard Dawkins, Christopher Hitchens and other atheistic thinkers.
I'll think of more later.
