I think earning 1.5X - 3X the wage for the same job as one would in Florida overcomes the tax and COL burden in most cases for which this discussion is applicable. The lowest economic tiers are another matter: but their mobility is limited anyway.

Edit: also, bubble? In what sense? Tech? Sure: there's definitely an assumption about the use and understanding of tech here. Politically? Hardly--this place is an oddball mix of libertarianism, hand-wringing liberalism, apathy, and tons more. It's also not a cultural bubble; the exact opposite in fact, especially compared to Florida.
