On an hourly basis, you can earn more teaching the LSAT than as an Ivy League law grad. Mind you, I don't work 80 hour weeks, so I don't make as much on an absolute basis, but the work is more interesting, and I've branched out into LSAT books and an online LSAT course.
But mainly, I wanted to point out that the instructor is unreasonably arrogant. By comparison with his reference group, he's far from exceptional.
By implication, the Mensa cut-off is also far from 'genius'. Top 2% is 1 in 50.
