That sounds like it would lead to Corpo-feudalism, aka techno-feudalism. Some billionaires are working to accomplish this.
billionares love mass democracy because it is dominated by media and turns into one-dollar-one-vote, centralizing the government in an easily controllable power center
the solution is to have many centers of power and to distribute the corruption, which remains constant
Why do you think the corruption would remain constant? When you have more centers of power, each tiny oligarchy is fighting for their piece of the pie. If they don't do something unethical, some other group might outcompete them. Meanwhile if you have more concentrated power, those in charge can think long term and won't be immediately threatened by the competition.
