Yeah I guess this might be hyperbolic. But my sense is that quite a few quants make seven figures, and that people capable of being tenured research physicists could be at least in the top of that group, if not partners / executives at those firms, which I believe is often an eight figure job. If they could stomach the work, that is...
I agree that income is a joke but... more than seven figures as in eight? That's quite a lot.
