It may not be the country but the group of people you happen to find yourself in. I've known people (and groups of people) like that in the US and I'm sure you can find people like that anywhere. IMHO: the trick may be to find people who align with your idea of "better" as well as their want to make the world that way.

For me, the hard part is defining "better place" because I only have my own perspective to know what is "better." An example: I hate car noise, especially at home. I would love to see silent transportation everywhere, especially cities. There are even studies to back up reducing noise pollution for the greater good. However, for some people, having a loud car (or bike) is the best thing they can imagine. Some other people like the ability to have a loud vehicle without actually having one. A "better place" is directly contradictory between our world-views... and that's just one dimension of a place.
