So you don't do anything because you have a job you need to keep and a kid to take care of, but you're perfectly okay with moving to a completely different country on short notice?
Yes because one of those can get my face smashed in by a baton. Moving is a far safer option for my family.
Call it selfish if you want (hell, I'd even agree with you) but my priority is my family and my life. This idea that I have to care about "my country" is patriotic BS pounded into us to make it more likely to join the army.
The US, for better or worse, isn't a cohesive country of people interested in a collective, but a smash and grab of economic gains sourced from those who are forced to live in it and cannot flee to developed countries. You come to it, or stay in it, to make more income you would in developed countries at the detriment of everyone else.
Whether you believe the economic human factory farm that is the US is worth saving or preserving will be a function of your lived experience and mental model. "What are you optimizing for?"
