Getting people to pay for something isn't the same thing as making the world a better place. You'd need to figure out all the effects and costs of the service to know if you're doing good or bad. Tobacco companies sell things that a lot of people desire, but the effect on society is surely negative. Same could be true for social media and many other types of services, but we don't know because we're not really trying to figure that out. The only question we ask when we are starting a business is "are people willing to pay for this enough to make a profit?". We don't ask if the effect of that service is actually good for society or the world.

It's not the same and there are plenty of counterexamples, but it's aligned more often than not.

People want to stay in touch with those they love.

People want to have medicines to improve their stress.

Etc.

I'm not so sure about that. How many of the services and products we consume today actually increase our quality of life instead of just giving a small dopamine boost that before you would've gotten from simpler things?
