What's the difference between an extra large pizza and an artist?

An extra large pizza can feed a family of four!

Here's a great letter from the Globe and Mail from last Friday:

I’d like to make a modest proposal to solve some of our eco­nomic problems: Let's do a job swap," choreographer Liz Lerman writes at www.communityart­s.net. "We'll put the corporate ex­ecutives to work as artists while the artists run Wall Street." Some of the advantages, she writes:
Artists work ridiculous hours for no pay. And most of the artists l 'know will keep working until they get the job done right. Artists do not need fancy offic­es. In, fact, they usually work in the worst part of town.
Artists do not need financial in­centives. Artists do the work they do because they love it Or be­cause they believe in it.
Artists do not expect to get any­thing if they do a bad job. Except maybe a bad review.

Artists keep very tight budgets.
