Or so is a school of thought of contemporary political economy (read Why Nations Fail by Daron Acemoglu. et. al. )

Example: the cotton gin did not make for a healthier middle class, since the political apparatus barred access to capital (and human rights and civic participation) for so much of the population.

Since everybody now has a washing machine, fridge and vacuum, the profits fell and the manufacturing just barely sustains itself.

Since the founders / owners / shareholders extracted all excess profits, the companies became brittle in crises, causing them to buy each other until there is just about 1 per continent, possibly 1 in the whole world.

The only way to jack up prices until then, barred burying the whole planet under a pile of planned obsolescence electronics garbage, is to invent new ways to introduce scarcity. Like gating certain features behind a subscription fee.

And temporarily also to lay off as many people as possible, replacing them with automation.

Please elucidate how do you envision next win-win capitalism-based boom. Time savings to everyone have been driving the last one. The only area with a low-hanging time-saving fruit remaining is time on job. Which is exactly the time capitalism seeks to maximize for workers.
