It’s true, sales can be very lucrative, no matter what you’re selling. If a software company’s salespeople are performing and the company is successful because of it, nobody should be surprised when they’re the highest paid employees in the company short of executives.
Anyway, I don’t see the current RE commission structure continuing forever. Redfin and the like are probably the future. My wild guesses are that eventually agents will make a base salary plus a MUCH smaller commission, and the MLS will gradually be replaced by a public database.
