What's the use of creativity without productivity?

People are constantly whinging about creativity and how school doesn't encourage it.

I believe that productivity (the way you use your energy, time AND creativity) is more important that creativity alone. I can be the most creative person, but it is of no use if I can't find ways to channel that creativity into productivity.

And society doesn't encourage productivity. It encourages us to pay for what others produce, not produce ourselves. When many people produce, some will find the channel for creativity. If we don't produce, I don't think it is of much use if we are creative or not.
