Campaign promises and economic realities

Last week, Donald Trump tweeted progress on a campaign promise: Carrier Air Conditioning might not move 2000 jobs to Mexico after all. Does that mean American manufacturing is making a comeback? Probably not — although Trump will get headlines if Carrier stays in Indiana. Meantime, what's it like to work at a company that might or might not be there tomorrow? Is that what drove former Obama supporters to vote for Trump? In any case, they're faced with stark circumstances. Would infrastructure rebuilding help? Should it be privatized or financed with federal taxes?
