None of the issues you raise are inherent to individualism, you can find historic examples of community-focused societies that also have social classes and useless politicians. You also seen to be coming at it with a personal preference towards the community rather that the individual. There's absolutely nothing wrong with that and both have pros/cons, but course you aren't going to like the focus on individual freedoms. Oligarchy was also absolutely not the plan from the beginning. Washington set the standard for a two-term limit precisely because he didn't want to see it turn into a lifetime appointment. What we have today evolved over time, though I would argue or problem today is fascism rather than an oligarchy.
