First off "companies fleeing the state" is way overblown. A couple companies moved their legal HQ, but for example the Tesla office in California is still expanding. They just "moved" for tax reasons. But the people stayed here.

Secondly, I doubt many companies will leave given that all their competitors will also have to publish this information.

Its hardly the only state to do this. Many states that passed these laws already, such as Colorado, Connecticut, Nevada, Washington, New York, New Jersey and many more are introduced in state legislation around the country.

I don't see this as anti-business either. If anything, it makes it easier to investigate how your competitors are paying their workers and act accordingly.

Totally unnecessary. Just make levels granular so that there's never a large difference in the same role. Junior developer I, II, III, IV. Developer I, II, III, IV. Senior developer I, II... Then you can post whatever salary you want, just say that the candidates' experience and ability matches a different level if you want to pay them more or less. I don't see anything in the bill that prohibits companies from saying "your performance doesn't match level X, but we are willing to offer level Y".

Ultimately if companies want to give a candidate more money to seal a hire they'll find a way. If they don't want to pay a candidate as much they'll either just not hire them, or offer a different role. I suspect this will be a superficial change and nothing more.

The main outcome will be companies figuring out creative ways to abide by the word of the law while flagrantly flouting its intentions.
