The problem in this case isn't unemployment, and using unemployment to track it would be misleading. If small businesses die off, that means there will be less job openings for people to be hired into in the future. The US economy is already fragile. I'm not sure how it will cope with the kind of structural (long-term) unemployment that will result when too many businesses fold.

Per the article:

> While the businesses are small individually, the collective impact of their failures could be substantial. Firms with fewer than 500 employees account for about 44% of U.S. economic activity, according to a U.S. Small Business Administration report, and they employ almost half of all American workers.

It's appalling that all the focus in politics is on big companies and giving them handouts.
