From John Stossel's blog: Each state has different rules, regulations and taxes. It's confusing... but it's also a good thing. It creates competition. When one state does something stupid... people can leave that state and take their talent and money with them. Travis Brown tracked the movement of people between states for his book, "How Money Walks." Florida and Arizona are #1 and #2 in terms of gaining people... and wealth. Darcy Olsen, who runs the Goldwater Institute in Arizona, says Florida and Arizona win only partly because of good weather. Most of the gain comes from people moving to where the jobs are. Oklahoma didn't see many people move in... but then it lowered its tax rate. Speaker of the House, T.W. Shannon, said that turned things around, and now people want to live in Oklahoma. Erica Grieder, who wrote the book about Texas: "Big, Hot, Cheap and Right," says there is a lot Texas does... that the rest of the country could learn from.
