It certainly is in the interest of enterprises to provide value to consumers. But so too is to do that as cheaply as possible, in order to have the largest margins possible. The one to sell for cheapest will prevail. Even if that means making people work for the bare minimum that'll keep them alive and poisoning them with murderous materials in subhuman working conditions. Even if that means starving an entire ecosystem to death to grow some grains or whatnot. That's where regulation kicks in. It sets the ground for competition without harming the rest of the world.
We do not disagree. But you're believing mistakenly that I am criticising capitalism. While I instead am telling that like every powerful resource, capital too needs to be heavily controlled and supervised. If you live somewhere where the market and capitalism is not doing shady things to cut costs and sell cheaper, tell me which utopian place/planet you are at, so that I can join you lot. But in the real world lots of starving hands touch everything we wear and tap and click. Regulation is necessary so that one's life don't cost many others' lives.
I guess a lot of it comes down to whether we are satisfied with the state of humanity, and whether we recognize past progress as an overall good.
There's a confirmation bias at work. There are infinite examples of the market working suboptimally for one consumer, a group of consumers, or consumers as a whole. But the entire platform is built upon creating value for consumers. People choose to pay for goods and services they want. In another system, they could be assigned arbitrarily. Or even completely unavailable. Capitalism created things you'd never expect, like broadband internet access and social networking to name a couple.
