It's the nature of democracy that one vote equals 1/N of the population. That is not flaw with the individual. It just means that for his vote to actually means something, it has to be part of a social memetic arrangements and not cast in the abstract.

Of course with first past the post, the electoral colege, gerrymandering all conspiring to further devalue and skew the value of one vote, democratic voting becomes increasingly meaningless. This is not a flaw of the individual but of the system itself being corrupt.

And then we have yet another layer of disenfranchisement, which is republicanism, in which voters do not directly vote for their interest but vote for an agent which will have a long term in which to "interpret" whatever the electorate really meant by voting for him. He will do so in a space where the constantly fluctuating social memetic arrangements that got him elected are not really under his control and are only loosely, and shortly affected by his action.

This is because the control of the fluctuating social memetic arrangement is in the hand of the actual social elite, the people who own or have seized the megaphone of power and who grossly compete and collude. Largely to maintain the arrangement, usually in an uneasy peace with their immediate competitors. These people are not just politicials but media moguls, celebrities and other billionaires.

Any solution to this problem must look to the system as a whole and create incentives to the individual that will enable him to at least have his 1/N power over the state of things. Free of the influence of the actual social elite who fill his heads with ideas that benefit them rather than the individual. And in a way where individual can act collectively for their interests.
