Attitudes will change, as soon as it begins to affect these people personally.
But that obviously doesn't deal with the underlying problem--the "me" over "we" that you mentioned.
This is the sort of nonsense that makes me want to get out of this country. At the same time, I feel a certain amount of responsibility to help make positive changes. I wouldn't feel good about leaving people behind to deal with this shit just because I don't want to.
