On Monday, the Governor is going to sign a statewide $15/hr minimum wage bill. Incremental increases through 2022.
Currently, the major coastal population centers are already close to $15/hr. However, once you pop over the coastal range, cost of living gets closer to Nevada than to coastal CA, and small businesses there will likely not be able to absorb the higher costs, nor will consumers, when those costs are passed on. As I've always said, if you're going to control minimum wage (I'm a, "let the market decide" guy), you need to do it on a micro level, by city. You simply can't apply San Francisco wages to BFE Eastern CA.
My prediction, with CA having so many bleeding edge tech companies, is that by 2020, your average fast food restaurant is going to be staffed by 75% kiosks, 25% humans. Also we'll see a significant loss in what mom and pop places are left. It will also hurt non- big city people like building contractors, plumbers, etc., who can afford to hire $10/hr laborers and apprentices, but not $15/hr laborers and apprentices. Not to mention the potential laborers and apprentices who now can't find a job.
