Yeah, I heard that. Building those Monster Thickburgers would probably be considered "heavy" industry (boo!).

Have you ever heard the real estate business referred to as the real estate industry? I have. Many times.

Yes, there are quite a few like that. The banking industry. The insurance industry.

I don't know, I guess the people who work in those fields, assuming they are good and ethical employees, are industrious, work at their jobs with some measure of honesty, put in a decent day's work for their pay. It just doesn't fit the image of low-tech, blue-collar industry that oldsters like me tend to associate with the term.
