I think the issue is the US was founded by the wealthy for the wealthy. The solution is more than just writing your representatives, demonstrating, and getting involved with local politics. All these things can help the situation, but they won't solve the problem.
We really need a new constitution that protects our rights. We need to be able to say everyone is guaranteed access to housing, medical care, education, work, and privacy. We need to state that governments and corporations cannot manipulate people anymore. They are using the best of psychology and sociology science against us, this is unacceptable.
We have to ensure resources are fairly distributed, that wealth is spread out, and that our political institutions are designed to resist corruption. We have to look past popular vote for representation along with all the other systems we use that trap us in this never ending cycle of pitting people against each other for political gain. We need to move beyond having the government be an abusive entity representing monied interests.
Until we get these things we will never be able to move on. We will forever be trapped in a system that only values how much it can extract from us.
There is lots of money left, but after you used the cheat code and have unlimited money what is the point for a megalomaniac. The only way he can move forward is to make everyone poorer. This is the new plan.
