> My returns over the last 30 years obliterate their returns, because turns out investing in high flying companies will have much better returns than an index fund. You do you.

Only if you gamble correctly. And the '50-100x returns' you cite elsewhere are really hampered by a bunch of duds that lose money. Generic index fund would return ~1700% in 30 years. That basically means you have to pick right 16-33% of the time. That math just doesn't work out.
