Hi fern,
I don’t think nuclear fusion is a variable here. I have a degree from MIT and my particular interest was sustainable energy. I get the MIT press releases and they’ve made a lot of hype over the new Fusion initiative. From the hype, one could take the fusion project as the solution to climate change. I have my doubts and posted here. Nothing more.
I am not sure I understand your question. Perhaps I can answer this way:
In the mid 1900’s British Labour Party politician Aneurin Bevan asked
“How can wealth persuade poverty to use its political freedom to keep wealth in power? Here lies the whole art of Conservative politics in the 20th century.”
White Supremacy, patriarchy, homophobia, capitalism, have done, and continue to do, great damage to segments of the world’s population. Yet, while those with privilege have limited potential to effect change, I don’t see them as being the one’s who reap the major benefits of these unjust and oppressive dynamics. Those who benefit are the wealthy and powerful few.
As is clear from this graphic:

The Global North has a highly disproportionately negative ecological footprint while the Global South has a positive ecological balance.
Even if the populations of the Global South were completely eliminated, along with the bottom 90% of the worlds population, the ecological damage of the top 10% would still, eventually, make the world uninhabitable.
