I'm not sure who you guys think you're arguing against.
I understand why you feel like you're correct in naysaying and feeling like you're adding something to the conversation by being contrary. Unfortunately you're setting up a bit of a strawman, as if people who support Bernie feel like somehow he's going to magically change everything by himself. Bernie himself said that will not be the case, and you're mostly just arguing people who have little understanding of government, who honestly aren't even taking part in this conversation.
Bernie is probably the most likely candidate to promote the idea in your comment anyway, as he's the only candidate who I feel truly wants to change the system. So even in regards to your opinion your only real candidate is Bernie. He's the only one talking about political revolution, which is what would be necessary for real change.
