What is really needed is to have our current system be flushed out and replaced with newer components. The way it exists now the current system will always exist even when the old figures retire/die the ones that will replace them will likely hold the same/similar values as they did. Perpetuating the system for ages to come. It would also help if to become a politician it did not require you to have assloads of cash and already existing ties to power/cash to get your position secure. There's a difference between wanting to help and represent the people because you are one of those people, and the concept of selling yourself to people claiming to understand their needs but are simply scamming them to gain power in office and do fuck all to help anyone but themselves and those who they play "hide the bribes" with.
Yes. The problem with having a plutocratic/nepotistic regime is that the will of the people is not represented at all. There needs to be some connection, but if the people of the regime are to foreign, they become paranoid with increasing plutocratic/nepotistic tendencies.
This leads to the populus drifting away from the hegemon into hyperpolarisation and eventually fracturing the whole. The higher ups of the USA have now realized this and are trying to adjust. The problem is they themselves are quite fractured and maneuvering into a more stable direction might not be possible, them being too divided. I don't see them overcoming their paranoia, forcing them into a position where they simply can't get in touch with the populus which is quite incoherent itself. All in all its a huge mess, and it does look like they will fail in the attempt of holding things together.
Their next step is going for Ron DeSantis as a decelerating move. It is the same playbook as Ronald Reagan in the 80s. The 80s however where a time of a much more coherent populus in a way better condition. It seems inplausible to me that they will be able to make this trick work again this time. There is simply no ground for it.
