About 60% of government functions can be replaced by smart contracts via something like EOS. Tax revenue comes in, smart contracts are used to pay expenses in a way that completely transparent, robotic and accountable. Citizens vote for parties based on their smart contract platform. We will never be able to completely eliminate concentration of power and the resulting corruption but the impact of blockchain tech on governance will be like breaking up that group of rich entitled snots in highschool that do whatever they want with total impunity. I can't wait.
