Libraries introduce 3D printers to great acclaim

Montgomery County, Md. is using a $100 million revolving loan fund to develop more than 3,000 affordable housing units across the county. 

The United States did not wind up with a housing shortage overnight - several factors have played into the conditions that have created the current market. 

When counties' housing markets price out workers, they lose a population that participates in civic live, volunteerism and community building.
