Right. This is part of it. Real estate is still the largest purchase most people make in their lifetime, and there are tons of things to deal with: inspections, title companies, escrow accounts, taxes, etc. I'm overgeneralizing, but if you're selling a home and you're not wealthy, you are terrified to make a mistake that could wipe out a big chunk of your net worth if you screw up the sale, so you use a broker. If you're wealthy, you don't care about the 6% fee, and luxury brokers have already sold you on the value proposition of extra marketing and hand-holding from the days when you weren't as well off and buying your first home.
