The Real estate industry has never had a lot of so called “talent” that you are talking about. By definition real estate agents are salesmen. To be good in sales doesn’t generally require any particular technical skills or degrees. The same traits that make a good car salesmen also works well in real estate.
So, what will happen to all the real estate agents after the crash? The real good ones will continue to be successful in real estate, or probably any other sales related job they wish to pursue. The poor ones and part timers will get weeded out. I don’t see anything drastic happening here, just a natural cyclic shift in employment.
