The real problem is what to do with the problem-solvers after all the problems are solved.

Well, everyday arises new problems, that needs to be solved. Some problems take longer than others to solve, but after solving all the problems, the problem solvers have a problem to solve. They are out of a job unless a problems arises. So what do they do? They create an even bigger problem so that they may keep busy. That's how the world goes round, although problems have not come to stay, problems are created to keep the problem solvers, solving problems.
