If we're being charitable and assuming they aren't operating as part of some glowop: the motivation of Devon Stack, Eric Striker, Nick Fuentes, etc is that they believe that all problems in this country are downstream of the Jew, and that due to the state of how things are ("Basically Fine") conditions are not where they need to be in order to trigger a revolution that will overthrow them. They "seek" (although, since they do nothing, it's better to say: they want to see) material conditions deteriorate rapidly for White Americans and basically force White America to be pushed up against the wall, and they believe that at that point, White America will rise up and enact the Racial Holy War/Day of the Rope/etc that will end Jewish rule and thereby essentially fix all of the other problems.
This is an incredibly stupid mindset because we can see what happens when material conditions rapidly deteriorate for Whites and force them to "radicalize and revolt." It's called South Africa. You don't get your own White Ethnostate out of the bargain they envision of "things get worse = political radicalization." What happens is that things get worse and people become completely demoralized, and things keep getting worse in a feedback loop.
If we're not being charitable: They are all in some way, directly or indirectly, assets of the Leftist Clique whose job it is to spread demoralizing "blackpill" doomspiral narratives to keep what would otherwise be a dynamic and vigorous force of young men in a cycle of pessimism and hopelessness, so they never actually do anything and anytime something does start happening they clamor like crabs in a bucket to drag it down because "nothing ever happens" and "Zion Don is a Jew anyway."
