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?
This is a good, nutshell explanation of late-stage capitalism.
As far as the answer to “what’s the endgame”, I do not know. I suspect that many or most of these rich folks are so moneyblind that they don’t know either. Or, they simply don’t believe that their collective actions will eventually cause the system to fail.
But most likely, I think, is that they believe someone else will bear the majority of any negative impact. Of course this makes less sense in the face of a systematic collapse, but again: it’s probably very difficult to see when you have dollar signs in your eyes.
