Bankers these days are more popular than they used to be. A new poll by Gallup shows the banking industry qualifies for a Most Improved award in 2013, with an 18-point jump in its reputational rating. Banking still has something of a black eye, with 43 percent of Americans saying they have a negative view of it and just 33 percent having a positive view. But that's much better than the numbers from last year: a 53 percent negative rating and a mere 25 percent positive rating. Overall, it's the biggest improvement in any of the 25 industries Gallup measures.
