By young people you mean people 26 years old & up. Because under this LAW parents are supposed to cover their ‘children’ up to 26.
Some few rich parents may choose to pay extra to cover children up to 26.
Most 18 to 26’s will pay the tax (granted, they may get the money to do so from their parents, but that’s less money their parents can give them for partying, rent, drugs, or whatever).
Thanks kids! (No, seriously, I do feel bad for them.)
