I don't think you could do it quantitatively - you can hand wave away rents entirely with the premise of the question (global equal wealth distribution) and just look at labour and global production, but even then you'll run into issues around substitution.

For example, most of the world's cobalt is mined in horrific conditions by poorly paid children in the DRC, but if you were redistributing wealth globally (and therefore stopping kids having to mine coltan for poor wages) the impact on the price of cobalt and electronic goods would be fairly marginal, because capital investment through mechanisation would increase in the DRC, or Australia would go back to being the primary cobalt producer as it was historically.

You said most of the value is extracted by the bourgeoisie. I said that the way they extract it passes through the labor aristocracy. They could extract it without the labor aristocracy but they'd have revolutionary conditions on their hand. So instead they pay salaries from the surplus value generated by the periphery and then reclaim those salaries through rent, taxes, etc.

If the surplus value is retained by the periphery, the salaries cannot be paid from that anymore. That means rent cannot be paid from it, therefore we go through a potentially revolutionary adjustment in cost of living.

The problem is that there's very little surplus value domestically. Yes, historically the USA had industry, but they built it on top of genocide and land theft. Now, though, the USA doesn't make much of anything from raw to finished. Everything that it does make, like food, relies on major inputs from the global south like fertilizer. But more importantly, it relies on massive road infrastructure to maintain it's imperial dominance over the continent. That road infrastructure is highly dependent on global exploitation.

How did China build industry without imperialism? Self-exploitation. It did not retain the surplus value of the labor of its proletariat. It intermediated the flow of value but it did not revolutionize the flow of the value. It attracted capital investment from the global bourgeoisie explicitly by maintaining their ability to profit from exploitation, that is, extracting surplus value from the labor of the Chinese proletariat.

As China increases wages, it is partnering with countries who also have been exploited by the imperialists and it is intermediating that value stream now. This allows the Chinese proletariat to improve their conditions and the Chinese state and Chinese bourgeoisie to allocate capital without triggering destructive reactionary behavior from the global bourgeoisie.

The value streams are remaining mostly intact, the global bourgeoisie is still extracting surplus value through China, and China has not chosen to shutdown the exploitation of its people.

Which brings us back to the North Atlantic labor aristocracy. European society is unsustainable. They devastated their peninsula of Eurasia and had no land left to exploit, so they went to sea. They spread like a cancer all over the planet, but they didn't find anything to replace their land until they arrived at Turtle Island. Once here, the European cancer devastated two entire continents and the people on it. Completely unsustainable, just like Europe, but the land was vast. It's only been 530 years since then. Conditions change. The USA is a completely unsustainable economic system on top of a completely unsustainable settler system on top of a completely unsustainable genocidal system.

If the flow of surplus value were to stop immediately, America would face total catastrophe, and in the face of total catastrophe it would launch a massive war campaign, just like the Euro virus always has when faced with catastrophe. Such a war would be in service of maintaining the flow of surplus value for generations to come by destroying the productive capacity of the rest of the world, forcing them to rely on the imperial bourgeoisie for rebuilding and thus ensuring surplus value is extracted by the imperialists.

What would not happen is sudden domestic investment to build production in the USA and a re- proletarianization of the labor aristocracy. And the reason that wouldn't happen is because the capabilities no longer exist in ready form in the USA and because the native population and the formerly enslaved population will force the issue of liberation, forcing the USA to allocate resources to domestic control and genocide instead of production and reproduction.
