They need to break the states up too. Southern California $100 is a lot different than a Northern California $100. $100 living along the coast is a lot different than $100 living inland.
Now Central Valley life can be a lot cheaper than coastal life - no doubt about that. I have a vacation home in he Central Valley and everything we do here and for the home is cheaper. Painting, repair work, labor, gas, auto and boat repairs, everything.
