Some specific critiques I have are: the counterfactual math is doing a lot of rhetorical work it can't actually bear. "Haig-Simons is real income" is asserted, not defended against its well-known problems. The "virus" metaphor smuggles in causation the evidence doesn't support. Income concentration and political "oligarchy" are treated as the same phenomenon. The Oligarch Act pitch gets a free pass from its own author.
