ELKHART, Ind./WASHINGTON (Reuters) - President-elect Donald Trump goes to Indianapolis on Thursday to celebrate a deal that will keep 1,000 factory jobs there, but employers elsewhere in Indiana are laying off five times that many workers because of foreign competition. The decision by United Technologies Corp's Carrier unit to keep half of the 2,100 Indiana jobs it was to shift to Mexico has allowed Trump to claim credit after he held rallies during his populist campaign promising to revive the industrial base of the United States.
