I had a super cynical dystopian idea. Never got around to fleshing it out, so its stability is doubtful at best, but here goes:

So a problem with democracy is that advertising is a powerful force and the candidate with more money to throw into their campaign tends to win, not to mention various forms of bribery coming into play after the elections. A ton of money is being wasted on shady behind-the-scenes deals. Lets get rid of all that and bring it into the light!

• Get rid of elections AND politicians, since they are just middlemen. Instead create a kind of stock market for various spheres and levels of lawmaking and have megacorporations and other interested parties bid on those.

• Money that would have been secretly funneled into politician pockets instead goes openly into the government budget.

• Save more money on elections and government official salaries since there are none.

• Corps that make laws that benefit consumers get to use that in their advertising. Buy from ProcLive! The company that brought you halfway decent healthcare!

• Voting with you wallet ends up being mandatory. You don't like that Disney took away weekends? Give your hard-earned cash to Sony next time. They promised to reduce mamdatory weekly working hours to 65!

• Maybe sometimes a local citizen initiative manages to raise enough money to get governmental powers in a small town or something. I mean, probably not, but you gotta give people some hope, right?
