I hear you, and mostly agree with some of what you say. Though I take issue with the right families, those being the ones benefitting from the power. What I will point out is the gilded age, and how bad it was back then. Many of the same issues we have today, corruption, bribery, the net worth of the robber barons adjusted for inflation was probably about double the net worth of our current crop of scumbag billionaire villains.
I don’t subscribe to the hopelessness, and I do believe we can end this second gilded age. I just don’t see the ability to do that with either political party’s leadership. We have to reject them both equally while recognizing exactly the issues you’re pointing out with regards to the power structure and inequality. That is essentially what happened when we ended the first gilded age.
