Add to it factors such as that there were too many restaurants to start with, they are really not that essential for most people, many restaurants were operating even before with a very small margin, some older restaurant owners will use this situation to retire for good, and many employees will be reluctant to return to their old jobs.
Poor prognosis for restaurants and other businesses in the service industry.
Around here in mid-New Jersey, I would go into a pizza store or bagel place during lunch hour. And there would be a few people buying. I couldn't figure out how they stayed in business. Didn't make sense. Bakeries, Chinese restaurants, barbers, etc. Just too many. Even larger stores. There would be a huge CVS and huge Walgreen pharmacy store right across the street from one another. Then two more a couple of miles away. How much aspirin do people need? How much film are people developing there? You're going to see a huge shakeout when hundred of these stores start closing across the country with thousands of more unemployed.
I think the problem was money was too cheap to borrow and build. Now when they have to pay it back, and stores are closing, they'll be asking the government to step in and bail them out too. And the government will adding to the debt the middle class schnooks will have to pay for with their life's savings.
