Things are more expensive in some states than in others. Taking into account the variations in cost of rent, food, gasoline and all kinds of other stuff, the Tax Foundation created the above map using data from the Bureau of Economic Analysis to show the relative value of $100 in each state. The stuff you can buy with a Benjamin in California would only cost you $88.57 in another state. Take that money to Mississippi, and you could buy stuff worth $115.74.
The fascinating economic questions raised by a map like this one are too numerous to fully explore here. The obvious reason that people don’t move around from state to state to take advantage of these differences in price is that they can often make more money in their current job. This chart is a thorough exploration of where people are making the most money relative to the cost of living. By this measure, Rochester, Minn. is the wealthiest city in the country. On the other hand, variation in the cost of living is mainly due to rent, and building more houses would make living in wealthy cities cheaper. At the same time, Americans are also just moving less often than they did in the past, an issue Know More has raised previously. Encouraging people to move more often would make the economy more efficient overall.

Not bad FL, but CA and NY though.
