It’s both. The western economy is in a slump, people are getting disillusioned and that creates the perfect environment for populist ideas like Fascism to pop-up. The right has wisely noticed the power of social media and they’ve been flooding the web with propaganda, couple that with bad-faith actors like Russia taking advantage of the situation and you’ve got yourself a bunch of young, gullible people with no positive outlook for the future being dragged into all sorts of extremism with false promises of change for the better. Not to mention all the boomers coming out of their closets as full-on fascists now that the right has been extremely vocal in favor of said views.
