And right now what we really need are start-ups that employ people.
You're probably referring to this:
(KANSAS CITY, Mo.), March 7, 2011 – During the Great Recession, more Americans have become entrepreneurs than at any time in the past 15 years. However, while the economy and its high unemployment rates may have pressed more individuals into business ownership, most of them are going it alone, rather than starting companies that employ others.
According to the "Kauffman Index of Entrepreneurial Activity," a leading indicator of new business creation in the United States, 0.34 percent of American adults created a business per month in 2010, or 565,000 new businesses, a rate that remained consistent with 2009 and represents the highest level of entrepreneurship over the past decade and a half.
I haven't looked into this much but intuition says the internet has a lot to do with the single employer nature of start-ups. You can have economies of scale and compete with the likes of Walmart-Target, or your favorite duopoly, with a no employee enterprise. Employing others or not, I don't see how the highest entrepreneurial activity in 15 years is a long term drag (and that number is in real terms). To me, the high rate of sole proprietors is a sign of low capital start-ups (read: low risk), and many of the survivors will eventually grow. Despite problems that pale in comparison to the Great Depression, WWI and II, Korea, stagflation, and Warren Buffett-esque fear mongering over 1832 China, the future of America is great.
