We would have a wealth inequality problem if "things are bad, caused by wealth inequality" resulted in people fighting to make things better by fighting for things that would reduce wealth inequality. This is not what we're seeing.

We do have an anger problem because "things are bad, possibly caused by wealth inequality" has resulted in people fighting to make things better by angrily striking at random directions, a lot of those actually increasing future wealth inequality - so if we want to solve the actual causes (for example, wealth inequality) we'd have to tackle the anger problem first.
