Capitalism is all about inefficiency. Not at the level of manufacturing individual items, that is made ruthlessly efficient, things built at breakneck speed by minimum wage workers out of the cheapest materials that will technically suffice.

But on the output side it requires society to be extravagantly wasteful. Single use items, paid for, used once, and thrown away. Nothing can be shared, everyone must be forced/coerced into buying their own separate one even if each one is unused 95% of the time (look at how many cars are parked in any residential road at any time. A fraction of that number would be plenty to ensure what you wanted was always available if they were a shared fleet). Dedicate things to a specific task, don't make general purpose things. If single-purpose products aren't sufficient, make a no-purpose product and use marketing and advertising to convince people they need it.

Yes, it's in the nature of businesses to require profit, sure. But capitalism requires more, always always more. Mere profit isn't enough, it must be more profit than before, more profit than the competition, ever-increasing profit. Push costs down by any means necessary, increase revenue by pushing your products as hard as you can and driving competition out of the market. Investors won't be happy with only doing as well as any other business, you have to do better.

It's the same dynamic as with bitcoin. It started with everyone mining with a standard computer, but then someone built an ASIC to mine quicker, got a bigger share of the rewards, and then everyone had to do the same or it wasn't worth taking part. Now it's banks of GPUs. It's no longer worth mining any other way. Same with big businesses, you now can't get investment without the promise of huge and ever increasing profits. Decent businesses expecting normal-sized profits can't get that kind of funding.

And this is what runs our lives.
