Rand gives it a go:

Although family income grew throughout the decade, the financial benefits that the family might have realized were largely consumed by health-care cost growth, leaving them with only $95 more per month than in 1999. Had health-care costs tracked the rise in the Consumer Price Index rather than outpacing it, an average American family would have had an additional $450 per month — more than $5,000 per year — to spend on other priorities.
