The incentives are all wrong. You can serve up to 6 two-year terms in the Assembly or up to 3 four-year terms in the Senate, but regardless of which combination you do, nobody in the California legislature can serve more than 12 years combined across both Houses of the legislature. So we don’t have professional legislatures with long-term electability incentives or leadership goals, we have a resumé-building exercise…
That's a non sequitur. Creating long-term professional politicians is not going to create legislators competent in the various domains they legislate on. It's going to create politicians competent at being elected long term, whatever the means.
I don't know what the solution is for California, but I don't think it's that.
