Although housing prices have declined throughout the country, many of those expected to benefit from the federal stimulus still can’t afford to buy a home, according to the Center for Housing Policy, the research wing of the National Housing Conference. In its new study (Paycheck to Paycheck: Wages and the Cost of Housing in America) the center paid particular attention to those professions helping to build homes—construction managers, carpenters, equipment operators, long-haul truck drivers and construction laborers—and found these workers, except for construction managers, are unable to buy the very houses they’re helping to put up.
