Age is an exception. There are no protections for the young, only the old. There’s a certain age where (don’t know what it is) where you can’t be discriminated against, but below that you don’t have protections.
I mean wether SCOTUS found a right in the 14th amendment is neither here nor there. These sorts of things tend to come from laws passed by legislators.
The federal ADEA (the Age Discrimination in Employment Act) only creates a right of action for people over 40.
It’s a weird one for sure. I wonder, if age were a suspect classification like sex, if the ADEA itself would be unconstitutional.
