Pontificating on the voting populace's ineptitude to not vote R or D doesn't actually fix the problem. You live in AZ right? How's voting third party working out for you? How many libertarians and green party have you sent to the House and Senate?
And no, that's not just on them. That's on all of us. Their stupidity is affecting the rest of us. I have to deal with an inept Federal government that won't prosecute/regulate the likes of Wall Street, Monsanto, or anybody with military contracts. And in the mean time, those corporations keep fucking shit up. I'm a tad bit surprised I made it through the most recent downturn without losing my job like I did in the last one.
So, no, Monsanto isn't just playing the game. They aren't big enough to tank the economy, but turning a blind eye to "corporations gonna corporate!" is what got us the last 5 years. Unreasonable protests(no, I don't think GMOs in general are bad), Michael Moore style documentaries, blogs, etc are how people "vote" against corporations these days. Voting someone else into office sure as shit ain't going to do it. Unless you have 50+ Bernie Sanders stuffed away somewhere.
