Michael Dayer, the president of Jersey Shore Modular Homes, says the workers at Pennsylvania’s factories that build modular homes love their jobs.

They don’t have to deal with the work-unemployment-work dance that builders of site-built homes are often forced to do, completing a job and then waiting for the next one to come along. A typical modular home factory builds a few hundred homes a year. In other words, steady employment, steady paychecks and benefits.
