Especially in today's capitalism modern era basically, it's all about money. Which also means that we basically just live to meet demands, or something like that. Which automatically also means that basically we just live our lives just to fulfill what other people (or society) wants; not what we really want. Everything must be catered down to this shitty 'economic demands'. Nothing more. Which is very limiting, as in we can't really be nor do what we want (well unless if you're lucky/fortunate, which is not everybody).
What's the point really in living life like this?
Except "capital demands" boil down to the individual. That's what's great about capitalism (or terrible, depending on who you ask). Everything boils down to the individual. Individual wants determines what society produces when you form a collective of individuals. If people want iPhones, people build iPhones. And if you have more stuff to offer (that other people want), you can get more stuff that you want (provided you have a common currency).
Now unfortunately, under capitalism, you do have to provide. So I understand why you say it's depressing. You will always have to participate in a market economy unless you choose to provide everything you'll ever need yourself.
But it's also getting better. In order to eat, people 200 years ago had to provide 12 hours a day of toil on farms just to survive. Or in factories. Capitalism has progressed where you can work 40 hours per week in an air conditioned office, and that's how many people make their living. People have spare time now for passions and hobbies they couldn't dream of 200 years ago. People can survive and offer much less. And what people are forced to offer decreases every year.
In economics, that's called returns of scale.
Capitalism has improved the issue you've brought up. But I agree there's more work to do.
