General Discussion

From Energy Infrastructure:

The oil and natural gas industry directly employs almost 2.6 million Americans and supports 9.8 million jobs in America, representing 5.6% of total U.S. employment. For every 1 person directly employed by the U.S. oil and gas industry, an additional 2.8 jobs are supported throughout the economy.

Rounding off, that's about 6 percent. What a coincidence!
