California has the 5th largest economy ON EARTH. At $3.4 trillion (that means a lot of digits), it's the biggest in the USA, bigger than even NY by 60%.
Florida's economy is driven by tourism. Take away bogeyman Disney and the beaches of Miami, and those alligator farm tourist traps ain't gonna do much to keep that laggard afloat. In fact, Florida is a taker state, taking more from the Federal Gov't than it puts in.
Poor people flock to prosperous states for a reason. In fact, Florida is known for putting its homeless on buses with a one way ticket to places like California or New York. And yet with living being far cheaper to live there, you don't see droves of poor folks moving there, now do you?
