The fastest way to make the world a better place:

1) SHARPLY increase progressive taxation.
2) GUARANTEE the BASICS of life (food, water, shelter, health…)

The problem is that the typical middle-class voter is only concerned with  their own lot and not the lot of the very poor.  Thus, when you end up with a situation where there is no longer any true freedom of speech because everyone is chained to an employer,  society begins to reap what it sows.
