Ah, one of my favorite things to talk about. This will be a long one.

Depends on how things unfold. It’s hard to look at the imperial core without looking at where they extract from and how corporate colonialism would be affected by it. As capitalism progresses the countries that they rely on now for cheap labor and cheap resources will eventually develop and start cutting out yet again the additional labor and extraction value the capitalists get. They will start wars, manufacture crisis in those nations of course but as we’ve seen it’s no longer America or the IMF picking and choosing the aid of a nation under exploitative terms. Will the imperial core stretch itself out maintaining global hegemony? A lot of fellow Marxists I think underestimate the barbarism or efficiency of the hegemony it has. Up until now and what we’ve seen in Africa and Syria; the threat of the U.S military alone was enough to have entire fleets of tanks defect. Now nations are growing tired, weary as they turn towards other avenues and some certainly will fall into despotism.

The nations that break away from the imperial hegemony will determine the “material conditions” and changes that you will see personally, in my opinion. For the purposes of sheer speculation, imagine what would happen if Indonesia, a beautiful nation, fell into a military coup or had some sort of catastrophic disaster? The loss of the worlds leading exporter of palm oil. Just look at what it’s used for; all of our lives world-wide would change. Deadly wet-bulb temperatures could make nations like that near uninhabitable. Global supply lines aren’t flexible enough to reverse areas almost unhospitable to human life, nor the storms that would come with those global changes.

Self-interest will reign supreme globally. You will likely see the E.U begin to distance itself from the U.S, the time it happens depending on how current world events turn out. Even if Russia were to go on a full-on “offensive”, you’d have the E.U immediately start gutting itself to fund a defensive coalition and the fledgling military industries they have. The higher standards of life and protections that Europeans enjoy on average compared to Americans would quickly collapse I would imagine. People more educated than me on speculating on Europe could chip in.

Debt will become a problem. Eventually nations in crisis are going to want to cash in their chips and America loves it’s debt. We’re already seeing nations move away from the dollar and once that debt is called you’re going to see the dollar hurt. When will that happen? Who knows. Mind as well be economic doomsday. Interestingly enough, Japan owns the most U.S debt surpassing a trillion. In the United States if the debt is ever called imagine how many of our basic services would collapse? How much would strangle and die previously only surviving on meager subsidies?

From Cyberpunk RED Corebook:

*"When the collapse hit it was the elderly that were hit first; the millions of Americans who lived on pensions and investments. Seeing their life savings evaporate, they became homeless, or were forced to move in with relatives. A lucky few were able to re-enter the work force.

Many died from either violence or exposure from living on the streets. Sometimes it was treachery from within; Grandma’s silver dining set could buy a grandson a lot of chemical excursions from life’s pain. Some families pulled together or were forced into clan-like styles of living. Even homeless, some managed to make it, but millions died.

Both the World Bank and the World Stock Exchange were gone. Which meant the United States government had no one to borrow money from. Federal Bonds were cashed in at a rate so high that the government could barely print money fast enough. This made the dollar plummet in value and accelerated the process.

Assets of the executive branch, especially the military reserves, were committed in growing numbers in a Herculean struggle to control the violence spreading like wildfire across America. However, the struggle was futile as the unrest was not limited to “less fortunate” areas and neighborhoods, and could not be isolated. Let it not be said that the men and women who tried to save America did not fight valiantly. They may have saved millions of lives, but in the end, it just wasn’t enough."*

Some would argue that we’re already living in parts of this.
