The special thing about "solving problems" is you usually create many more problems in the process. That's the definition of a startup: a company, when solving one problem, creates five new problems in the process due to imperfect foresight because everything hasn't been done before. Hence, hiring, growth, jobs, expansion, ....
Startups could be called "things that didn't exist before that are creating more problems to solve than existed before."
