All problems you described can be essentially solved by a simple thing. The votes just should not be equal. Our computers can have any algorithms for that. No, I am not speaking about non-equality of people. One of possibilities is to give more votes to those who intentionally pay more taxes (in percents from their salary) than others, i.e. help run the government more. It automatically means that they think more about the politics and care what is happening. Another possibility would be to give more votes to people who have more achievements (i.e. higher education, science degrees, something strictly measurable). Maybe the final solution is a mix of these two possibilities. What also is extremely important is a possibility to take my voice back when the elected person does not act as promised. Why we have no such possibilities? Then can promise whatever... I should note that these thoughts is just a first approximation and should be improved. What is important is I see no problems in "stupid average person".
