Hmm... It seems the major factor is simply overbuilding. "Overbuilding in one year leads to lack of building in subsequent years". As building homes is a big cause of temporary job growth. Also, I doubt long commutes lead to higher unemployment rates, as the economic pressures would step in. Companies hire to meet consumer demand. If they need workers, they'll raise wages, or open satellite offices where the workers are. They don't just stop hiring & let their production go down when they have orders.
