I'm hoping to pull the trigger on my Plan Exodus this year, and for the reason you mention.
Not every Californian can exit easily. Many are tied to jobs or businesses that can't easily be transferred. That's especially true if you own the small business.
And the Plan Exodus really only works for those Californians who own their own homes and have seen dramatic increases in their value.
But for those that do, and can find work in other states, it's almost a no-brainer. In fact, for those nearing retirement, it's a way to have a better and earlier retirement. The money you have left over from the sale of your California home and the purchase of your retirement home elsewhere could be sufficient to live on without the worry of finding a new job.
