It's something I've thought about before, too, and discussed with others. If we were to unleash our civilization upon the galaxy, as dysfunctional as it is now, well we would definitely not be a positive influence. If anything at our current state we'd be pretty similar to the aliens in
Independence Day; rapidly expansionist, destroyed our home planet by basically strip mining it, now we continue on to suck other planets dry to fill our need for greater power.
That being said, I really think the majority of the world's problems today are caused by the mistakes of a few people with very centralized power. Most of them I don't even think do it maliciously; I think from bottom to top (which IMO is a structure that should no longer exist and be "accepted") most everyone's trying to do "the right thing", but most of them are just bollocksing it up.
Eh, I still hold out hope for our confused and stressed race.
