I don't think the article necessarily does that. It just says that those who earn a lot in California seem to want to leave. Maybe they'll make less in their new state. It doesn't address that. Of course, as cali taxes go up, less income in a cheaper, lower tax burden state, means that the choice is now between two similar levels of quality of life, so it wouldn't be hard to come up with a causal model for the migration even if high earner was not an intrinsic trait.
