That seems to be often the pitfall with socialism-within-capitalism as often done in California imo - many of these socialist-ish policies only work if there's no easy "escape hatch" or it's at least uncommon. But not having access to private alternatives also often goes against free-market ideas.

Afaict, the wealthy and/or well-connected often "drive" the quality of public services - they're not going to insist on improvement if they can easily check out and pay for a private alternative.

I'm not saying to stop private alternatives, just that policies that might work other places probably don't work 1:1 in the US.
