Id argue it's an entirely different issue. Our country has no problem with violence, the numbers make that abundantly clear. I feel the issue more so stems from a lot of people here being relatively indifferent to things that don't directly affect them. Many, if not most Americans are rabidly individualistic, they care about themselves, and a very small circle around them with everything outside that small circle being the "others" those others being the ones they blame for all their issues. As long as nothing negatively impacts their small circle they care about, they don't give a shit.
That individualism in a lot of places itself stems from how rural and spread out a majority of the country is. Shit, even for me to go join a protest at the Capitol of just my state is a 3 hour drive each direction, and I don't even live in one of the bigger states. This country is so spread out in many areas that it's hard for many to care, let alone actually get involved if they do care.
You mix that individualism with a lot of really, incredibly stupid people, im talking half of the country can only read at a 6th grade level or less, and the fact that a large swath of people are living paycheck to paycheck and literally don't have the time or resources to get out and protest unless they'd like to be homeless without Healthcare, and this is the result you get. There have been tons of protests, quite a few of which have gathered some pretty good traction, even if its not shown in the media, but getting something going en masse in this country is nearly impossible.
I see it as less self interest, and more self idolization. As much as people here complain about "being broke" nowhere in the world do people on average have more expendable income than in the US. The price of eggs, or much of anything else for that matter, outside of a hyperinflation scenario, is more of a mild inconvenience to most people here than anything else. Sure, people might have to cut back a little elsewhere and do something horrible like skip a yearly phone upgrade to the newest $1500 phone they don't need, but they'll be fine.
Why i see it as self idolization rather than self interest is because what i see is moreso people just attempting to fellate their own ego, with a lot of people in this country, especially in more rural, conservative areas like I'm in, are people that are broke for reasons that are all but entirely their fault, but they don't want to blame themselves, trump and Republicans give them someone else to point the finger at, and they roll with it because in their tiny, buttery smooth little brains, to them if there's someone else to blame, and we fix that, then their lives will get better without them having to change what they're doing, and they like that more than putting the fault where it belongs, on themselves and actually fixing some of their own problems. In their heads, they'd be doing great if it weren't for x, y, z, that's completely out of their control, because they're doing a great job, its "those other people" over there causing all the issues, so it's "we need to stop those people so my life will get better without me having to do anything, because i'm obviously not doing anything wrong"
