Let all of that go. What really makes us happy is pursuing what we love. Some people are good at making art. Some people are good at making money. Some people are good at making furniture. We all have a purpose. We can't all be the same. But we are all needed in some way. We are all needed to make the world work. Look a bit outside your own sphere, and realize that all of us are helping in some way.
And of course, there are bad apples in every bunch. That doesn't mean that any one profession is all bad or all good.
I like the way you think!
