This was explained in the other post which I will reproduce here:
"looking at history of the US, the only time the people at the top ever gave any semblance of crumbs to everyone else was when they knew they were in deep trouble and were forced to part with whatever little they could give to calm the masses.
Think of Medicare, Social Security etc. We saw it again with Obamacare. The country was in a rage so out came the bare minimum. Elimination of barbaric things like pre-existing conditions in exchange for guaranteed income for the insurance companies. Absolute breadcrumbs but it was something.
We just need something like that on a worldwide level. Maybe China rising will finally put pressure on the US given that the EU never amounted to much more than being a US vassal state."
We saw the best of the US system during the cold war. The system had to prove itself. Im not advocating for communism nor Chinese style fascism just more competition.
The third world is already taking advantage of this situation. Nearly every country in the global south has been negatively damaged by the US or Europe at some point. They don't have many options other than to tough it out and hopes the West leaves them with whatever scraps they can get by. If they got too powerful, then the West topples them over. See Pakistan or Bolivia as a recent example. Now China has entered the scene and it has provided the ability for countries to start playing the US and China off of each other to see what they can get out of both countries. Djibouti and its military bases is a small example but we see it with countries like Brazil and Pakistan as well.
How would this help the middle class in the US? Well if the elite in the US start to think they will lose out they will start to enact change that will bring the middle class up to snuff in order to better compete...and lets be honest for a moment, whatever they say goes.
