Cnt 20121201 | Technology | Energy And Resource· Politicians are for Mom, the flag, apple pie and babies, too. But they generally don't have to put their money where their mouths are. Manufacturing in the United States has been written off as a dead issue ever since the 1990s, when companies started closing plants and offshoring jobs to "low-cost countries" such as China. Well, China isn't so low-cost, now.
