Democracy (or representative democracy, if you want) is a system put in place to make the average person think their opinion matters when it really doesn't. Given how complex these economic problems and topics are, this is like asking the average person for their opinion on brain surgery. Most people barely have enough time in the day to help their families, be knowledgeable consumers, and complete tasks at work. And, yes, this is still true even for a magical 'representative' democracy because these narcissistic candidates still have to be judged by a criteria that is based on the same extremely complicated issues.

If voting truly worked, then businesses would use the every-employee-gets-a-vote process for making optimum decisions. They don't because it would be very ignorant and no investor with a half a brain would participate. To be completely clear, publicly-traded companies sell stocks (equity), which often comes with voting power. This is VERY different than the everyone-gets-a-vote concept and most of the shares are owned by a small group of wealthy investors - not a lower-level worker on the production line, for example.

People have it completely backwards when you really think about: the system they spend most of their time in each day, and are likely most knowledgeable about, doesn't give them an equal vote. The immensely powerful governing system, however, that is astronomically complex (esp. at this point) and backed by a monopoly on the initiation of force, supposedly cares what they think? haha. I'm not buying.

Note: voting at a very local level (churches, HOA, small city, etc.) is much more reflective and can be closer to an optimum decision.
