If you've got a really bad dictator, or an entrenched feudal system, then a revolution is probably worth it. If not, you'll probably end up with a dictator, and there's a chance they won't be so benevolent.

There's genuine problems with US Democracy. The lack of a good voting system (preferential, or better still - acceptance voting) means a stable two-party system.

Statistically, protest actions can be beneficial, as long as they don't go too far. No politician wants angry people on the streets. Media tends to cover it. It's a good way for a minority of people to have a huge impact (for better, or worse, depending on whether you support what the protesters want).

The problem is, a lot of protests are pretty much zero sum movements. They are things which half the people want, and half the people don't want (environmental protection, gun rights, gay marriage). A protest for something which would be popular, but most people don't really think about could be more useful.
