Something tells me that you benefit daily from the efforts of people who had difficulty earning a living from their craft at some point. Do you listen to music, watch television or movies, appreciate art, read books or web content? The creators of those things didn't all start out as highly acclaimed millionaires. Most of them spent years making things that weren't valuable to anyone.
There are an abundance of people who are capable of earning a living through a variety of work. There are very few people who are capable of consistently providing you with a few hours of diversion or entertainment. Do you really think that the world would be a better place if all of those lazy creative people got jobs at mcdonalds instead of making things that bring small moments of joy to billions of people? There would be no books for young children to read, no songs for teenagers to get excited about at their first dance, no movies for old people to be nostalgic about. It takes a lifetime of work to hone the skills necessary to create those things, and a lot of financial and personal risk that most of us aren't willing to assume. I don't know if a 'creative tax' is the right solution, but we could all be a little more understanding.
