In addition, when people say "solutions" what they mean is "something that doesn't inconvenience me or require me to do anything".
However if you want "real" solutions, here are some:
1) Start denouncing ALL religion as the force for stupidity that it actually is. "I believe in an imaginary sky being with no evidence and you can't convince me otherwise" should be LAUGHED AT as the absurdity it is.
2) Get everybody off of petroleum so that there isn't any money for people to fight about over in the middle east.
3) Quit supporting dictators and bombing countries for geopolitical reasons.
4) Start fixing double digit unemployment rates instead of making them worse with "free trade" agreements that only allow companies to use open borders while preventing workers from doing the same.
5) Make mental health care a much bigger priority than it currently is.
Unfortunately, these solutions don't feed into people's preconceived biases and xenophobia and don't put more money into rich people's pockets. So they are all non-starters.
