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?
Not money, power. There’ll always be affordable consumables: clothes, food etc. It’s just the quality will go down to accommodate how squeezed the consumer is. But the limited resources: a stay at that resort, a home with space and good schools, the seats at the sports game etc those the prices will continue to race away. Which is just a different view of power (choice/control) shifting into the hands of an increasingly small proportion of people. Those places will still be full - but the chance of getting to them for the average person will grow dimmer with every passing year.
