Welcome to TOTV!!!
Guesstimates seem to be that around 60% of the residents are full-time. All I know is that the volume of people in TV increases dramatically during the wintertime!
Part-time work: If you are in a medical related field, you'd be in fairly good shape for a shot at decent employment. Other than that, reasonable wages seem to be hard to come by around the area. If you have something unique to offer, perhaps some type of self-employed small business would be good to consider.
Middle class? To me, TV strikes me as being a perfect slice of middle class America.
