There is no 'right' vs. 'left': it is the oligarchs against the rest
Rich vs poor is even less meaningful divide than right vs left. For instance i am not rich but my goals are much better aligned with goals of rich people like Elon Musk and Aubrey de Grey, than with any of poor people.The solution is not to take money from the rich, but to make the government more transparent and more inclusive. Now we only can vote for unknown bundles of policies in the form of people, and rich people can pay to change the bundle after it is voted in. The solution to that is to use e-voting to be able to change your vote for separate issues when you do not agree with the vote of your representative.
