Here is a quote from a book I've been reading named "Smart Power" by William H. Kemp:
"Family budgets are strained from the rising costs of living: taxes, mortgages, car payments, and energy bills for homes and vehicles. As a society we rarely consider the source of these costs. People hop on the bandwagon of the middle-class dream fueled by two incomes that make it happen. Large homes in the suburbs require enormous amounts of heat, light, and air conditioning, and many have two cars to get to distant jobs. All of this eats away at our precious discretionary income and our free time".
