...or so I thought. There are several problem with direct democracy: (1) Most people are not expert at things like foreign policy, economics and so on. (2) Many people can be heavily influenced to vote either way by creating powerful PR campaigns. (3) Most people have no time or capacity to digest tons of dense information to get the background. (4) Some information needed to make decision must remain classified.
This paper actually proposes a viable option here that works around many of the above issues. Instead of delegating all decisions for next 4 years to one person, we delegate case-by-cases and for arbitrary time length. This allows, for example, for a real economist to be elected to make a economy decision or nuclear scientist to be elected for Iran deal like decisions and so on. It might work. The bottom line is that we can get rid of arcane pre-Internet political system of senators, congressman and presidents.
