I don't tell people what to do with their lives and the thought of a well-intentioned bureaucracy doing so doesn't thrill me (perhaps from being placed in all the slow classes against my will as a child I am biased here). I like the free market for jobs. Empower people to make their own choices. Give them free community college even. But let them make their own minds up.
California could turn a lot of its secondary cities into job markets as well as suburbs for the major cities if they could build cost-effective mass transit. It seems incapable of getting that job done though so it seems like the only alternative is remote work, and without a cultural shift, that is piecemeal solution. Also look at what happened to SB50, shot down by effectively friendly fire from NIMBYs, not the conservatives.

I can only see two that are well within the range that might be covered if all the other safety nets fixed individuals that had become injured or otherwise unable to work (this is assuming we have MUCH better tech, like Star Trek / Orville level tech, to actually repair all types of damage).
Housing: This is more a choice made by the irrational market, not so much by individual humans. Yes there is less expensive housing, but it's usually not located near jobs or has a high externality / transaction cost of somekind. Referencing the source article, Japan does have a fantastically run transit system that is also reasonably priced. That does extend the range of available locations.
Jobs themselves; do you think that job placement systems are not a better idea instead of being "hired" to "look" for a job (which should not be ANYONE's primary life skill!)? If an aptitude test shows that there is untrained area that skill could be acquired in, getting that skill might be the assigned 'job' instead. (retraining/education)
