Holy shieet, $30k? Kids are "on their parent's plan" here until 18 years old, meaning that the parent doesn't pay extra. My parents have never paid more than €2500 per year for our family of four back when I still lived there. As a student, I get €85 for my €95 plan (no dental though) from the IRS.
Welfare state, man. Doesn't kill me that's for sure.
