Would an Athenian from the 5th Century BCE approve of our present day government?

In the Athenian times, the voice of the people was highly valued. Having it that one mans opinion could actually have an effect on the entire population. Now, the system has changed completely. Our representative democracy, gives one man the power to “rule” over the rest of his country. We elect this ‘president’, but other than that we don’t really have a say in the ultimate decision. We vote according to the man or women that represents our case, thoughts and opinions the best, and hope that they will com out on top, ready to take their position in the white house. But of course we are let down by who we thought would do the best job, and they end up not taking action on all of the situations they said they would try and fix. So now, we approach the ultimate conundrum. What can a person in their everyday life do to fix the other situations they feel need handling. Nothing. An Athenian would here be able to interject, and show us that their government was better, and catered to all the peoples needs. Without one central position making decisions each individual could pitch in their ideas making sure their voice was heard.
