The December jobs report speaks volumes about why the housing recovery is not as robust as it should be, given still historically low mortgage rates and still relatively low home prices. Specifically, the weak job participation rate, falling to the lowest level since 1978, according to the U.S. Bureau of Labor Statistics, explains why so many are barred from home ownership and why others in trouble on their mortgages are unable to save their homes.

More young adults are going back to work, with employment rising from below 75 percent earlier last year to just above it in December. Still, the number is well below where it should be. Wage growth also came in at just 1.8 percent for all of 2013, below the inflation rate, according to the BLS.
