The message is “hammered home” that refugees must find jobs and pay their bills, says Ruben Chandrasekar, head of the IRC’s Baltimore office.
I encountered this sentence when I read the economist. Does "hammered home" mean to build a home?
This is the whole paragraph:
The message is “hammered home” that refugees must find jobs and pay their bills, says Ruben Chandrasekar, head of the IRC’s Baltimore office. Few need telling. Refugees “know what it is like to lose a home”, so rent is the first bill they pay, he notes. They “penny pinch” to build up savings. Much talent goes to waste: refugees with advanced degrees work as car-park attendants or wheelchair-pushers at Baltimore airport. But still the city has much to offer. Houses are cheaper than in Washington, an hour to the south. Unlike many suburbs, the city offers public transport and a diverse population. Such diversity is an economic boon as well as a comfort, providing niche markets for small businesses. Baltimore is now home to Nepalese grocery shops and to a car service that takes Darfuri refugees to work.
