What? No. Anywhere outside of the major cities, 90k household income is middle class. Not upper-middle, but decent house in a decent school district, able to pay the bills middle class.

We live in Norfolk, VA on about 110 k a year for a family of five, not the cheapest cost of living area but far from the most expensive, one full time professional and one part-time, safe neighborhood, two decent cars plus a beater for the teens, saving for retirement, not wasteful with money but not worrying overmuch about money day to day, yearly airfare-plus-hotel vacations on our anniversary.  We're not wealthy, but if that's not middle class I don't even know what your definition is.
