The problem I see is that the US has some very serious and widespread flaws. The live and let live attitude doesn't push for resolution to these issues.
If we say for example the police system is not working as it should and many people are dying or being locked away unnecessarily, how do you fix this when the leaders of your country are unwilling to do anything. The only options you have make you one of those 'identity politics people'.

We have to find and grow new leaders! :)
My general comment is: please, pick one issue you care about, study it, find the leverage points, and make time to get involved. This might mean joining an organization, volunteering, making a tech project to share what you've learned -- even running for office.
Based on your username, I would guess perhaps you are already involved to some degree around pollution or environmental issues [1]. Let me know if you want someone to bounce ideas off of. I also can offer this perspective: ongoing dissatisfaction, properly harnessed, can be a great motivator for change.
