If they secede, they will still need the goods and services provided by the 99% - I doubt that many janitors, mechanics, painters, secretaries etc. are in that

If they secede, they will still need the goods and services provided by the 99% - I doubt that many janitors, mechanics, painters, secretaries etc. are in that 1%. They'd need to have these servicepeople commute in and out of "rich California" every day from far off, and they probably wouldn't want unsightly public transport, enormous highways, high-rises, or low-income housing cluttering up their little paradise, so commutes of an hour or more would become normal. That would never work.
