This is a US map showing the relative value of $100 by state. Money buys significantly less in California, Hawaii, DC, Maryland, New York and New Jersey. Money goes the furthest in Mississippi, which, coincidentally, is also the fattest state. Apparently because you can always afford to buy an extra cheeseburger.
Thanks to Lindby, who agrees the states where money goes the furthest also seem to be the states with less fun things to spend money on. After all, a person can only sit at home drinking and gambling online for so long.
