I just don't get it. Why are you ignoring that people with money can directly influence legislation? Why are you ignoring that capitalism directly rewards greed, explicitly makes it to be a virtue, and therefore breeds people and an environment that will automatically want to challenge democracy?
I don't understand how you can think that the idea to stop steering some people towards greed, and some toward a position of submission (by making it so that your life depends on you working), how you don't think that that will have direct repercussions on the mindset of everyone? People will think it's the norm, that's how it should be -- you have bosses, you have workers. Workers listen to the bosses. It's completely incompatible with democracy, because in a democracy, everyone is the boss, and everyone needs to understand that we're all equals, and that the responsibility lies with us to change society for the better.
Instead we get a sick culture, where people are utterly perplexed on what to do, who to vote for, because our entire mindset is that of worker and boss, not that of equals working together. That's not how humans work, it only breeds strife. It doesn't make any sense.
