There's an old saying: Those who can, do; those who can't, teach. A similar idea underscores the debate over wealth taxes in California and elsewhere: Those who can, build companies. Those who can't, devise ways for the government to take shares in what others have built.
This new version might sound unfair until you listen to Rep. Ro Khanna's (D–Calif.) pitch for an allegedly onetime, 5 percent wealth tax on California billionaires, tied to November's vote on Proposition 40.
