Corporate culture is based on constant growth and ever increasing profit margins. Eventually they’ll amass so much of the wealth that most of the lower class won’t be able to purchase anything other than essentials like food.
No new cars, no tech gadgets, no fancy dinners, no vacations, no disposable income.
When we get there the economy collapses because there’s no money going into it.
The profits stop rolling in, unnecessary goods stop being produced, and the luxury goods producer’s shut down.
At this point the money they worked so hard to hoard becomes worthless because they can’t buy anything with it.
What’s the endgame for them if their current path takes them to a point where their assets are more or less worthless?
Ditch the planet, let us have the wastelands, if they can’t just execute us first, or starve us to a more controllable population level. They want it to be them, and a small number of us to do the jobs they couldn’t or refuse to automate. This is the only answer that makes sense with everything they do. They aren’t stupid, they aren’t trying to destroy their own habitat, so their end game either doesn’t include us, or doesn’t include the planet entirely.
