"Better"-"worse"; that's all subjective. One man's paradise is another man's hell- or something. Anyway, some people think that humanity has a biological trick up it's sleeve for when the population reaches a certain critical mass. Some say that the species will almost simultaneously "awaken" and it'll be an end to war, greed, poverty, etc. Who knows, I just try to take care of my little corner of the world.
I think the ordinary people should stop believing the lies and propaganda that all our governments feed us, get to know and understand each other, it should start with us.

The simple answer would be a net-gain in quality of life for all people. We can't coherently answer with anything other than life being happier for everyone. Such can of course be achieved through cooperation which can be facilitated by empathy and actualized by conscious impetus, maintained through the perpetuation of life-advancing memes and paradigms. Such can be harmed by evil which can be facilitated by greed and irrationality, or it can simply thrive through egotism or apathy. Of course that's hardly an exhaustive assessment.
While that would certainly make for a better world, humanity by nature will never be satisfied with the status quo and your answer would fast become insufficient. The logical progression forward would then be to pass laws against kiddy actors on the Disney channel pursuing musical careers. Actually destruction of the disney channel itself would put an end to a countless aesthetic monstrosities in one shot.
