I don’t have the data to dispute the validity of your three industries but I’ll ask if you can provide evidence that hospitality, government, civil service might not equally weight into the equasion.
If I drive around La Jolla, Carsbad, Carmnel Valley, Scripps Ranch, Poway, Ranch Bernardo etc I see nice cars. If I go to National City, El Cajon etc. I may not see the same cars.
I would venture to say that all those do nothing real estate jobs probably were doing something before they got into real estate. Real estate paid better so they transitioned. Now that it is not they more than likely will transion back to what they were doing before. For many in the real estate community they have jobs ans did Real Estate on the side.
