For context, from the SBA’s advocacy page (2019):
“ U.S. gross domestic product (GDP) is the market value of the goods and services produced by labor and property located in the United States. Across the 16 years from 1998 to 2014, the small business share of GDP has fallen from 48.0 percent to 43.5 percent. Over the same period, the amount of small business GDP has grown by about 25 percent in real terms, or 1.4 percent annually. However, real GDP for large businesses has grown faster, at 2.5 percent annually.”
I have not critically considered whether or not these statistics are the best indicator of the most effective contribution to the economy (or society).
