Didn't see this Michael Moore video [1] until after the election, but it pretty well describes why I voted for him. I'm doing pretty well, but I have a blue collar background, and the people I grew up around weren't.
Didn't really figure he'd win, but my dad had died earlier in the year, and I figured he would have voted Trump, so I did it for him.
Wasn't really a "burn it to the ground" thing in a literal sense. Basically what the end of the video clip says: "It's going to be a big Fuck You to the establishment. And it will feel good."
And it did.
