But the claim here is just wrong. Being rich and powerful doesn’t make them automatically accountable for everything.

No, of course not. No one is responsible for everything.

But, as a very quick and simplistic example of what the post is saying, if someone hates immigrants because “they took our jobs,” that person is missing the very obvious fact that employers are the ones hiring people. Immigrants can’t “force” that. And of course even that employer is responding to pressures, both systemic and from above them.
