I appreciate PG's writing as always.

I'm skeptical that the super-rich are only generating 5% on their money. My anecdotal experience is that it's usually north of 15%. They have access to investments that main-street does not.

If we plug in 15% instead of 5% in PG's reasoning, the effective income tax increase is quite a bit lower.

There is a footnote discussing this point; he uses 5% as the risk-free rate.

Is 5% risk free even available to the little guys?

No.
