The death of brick-and-mortar retail

First, it was Main Street. Americans stopped going to their neighborhood diners, grocers, haberdashers and five-and-dimes, shifting their business to big malls, and blighting the central business districts of towns and cities across the country. Now it's the malls' turn: Americans are snubbing them, and flocking to shop on-line, mostly at Amazon. Will brick-and-mortar retail survive?

More than 8,000 U.S. brick-and-mortar stores could close this year, twice the number as 2016, analysts say, because of plunging sales. Among the chief victims are retail workers: Amazon says it's adding 100,000 employees, but a multiple of that number have lost their jobs in recent years. One in 9 Americans work in bricks-and-mortar retail, almost 16 million people in all.

We asked five experts to weigh in on whether anything can stop the wiping out of brick-and-mortar retail and the jobs they support:

• Kirsten Green, founder, Forerunner Ventures: Online shopping is no fun
• Stuart Appelbaum, president, retail workers union: Retail won't die, but it will change
• Oscar Yuan, president, Ipsos Strategy3: Amazon spurns Gucci shows
• Joseph B. Fuller, professor, Harvard Business School: People want to see each other face-to-face
