The recently withdrawn public offering for WeWork (leaving aside its other complications) has resuscitated an argument in some quarters about the propriety of dual-class stocks. The company’s proposed securities structure would have given its founders voting power outsized compared to their actual financial stake.

Lyft’s recent offering involved similar unevenness. The ridesharing behemoth debuted with a structure that gave its two founders 10 votes for every share, resulting in 50% voting control of a company in which their economic ownership is closer to 5%.
