There are fundamental differences between allowing minors to access health care that they require in a timely manner and letting a 19 year old rent a car.
Healthcare should be a right afforded to all people. Privileges are not rights and it is perfectly reasonable to restrict them based on age.
I don’t hate you for your opinion, but I do think you are misinformed on the subject.
A law firm capable of handling such a suit would probably bill at a rate of $2000/hr, or more.
If your numbers are right, then they could afford to pay for 20 hours of work. That’s probably not enough to even file the suit. Again, this assumes your numbers are right but even if they were 10x this it may still not make sense to file a suit.
Unfortunately, I don’t think the math works out in their favor.
