I think you have it backwards. Wealthy already have all the power they need. Everyone else has zero power, unless they organise, pool their resources or at least choose to move in same direction independently.
It’s a matter of phrasing. We all have power available to us if only we organize. If we choose not to organize we are letting the wealthy have the power.
But anyway I agree with you that we need to organize. Voting with our dollars as atomic individuals works in limited ways but won’t change things on a large scale.
