Quantum does not mean that the universe runs on a principle of random anarchy. It just means "a definite amount". It was originally used to explain the reason excited atoms gave off well defined and precise wave lengths.
I asked myself that very question not long ago. In Sweden the garbage men went on strike a few months back. It turned out that their employer wanted to change their routs so they would actually work around 8h a day instead of 6h. And as the strike progressed you learned that the 6h the garbage men worked actually gave them more money than the ~9h I work as an engineer. Sad but true.
