It'll not happen for anyone currently alive that's for sure, it's hard to explain but American's view the world differently to everyone else, as a Brit married to an American and lived in the US for more than a decade I still don't understand why things are the way they are.
It's the 'land of the free' - free to be expoited, and they seem to happily go along with it, in the UK , mandated by law, you are entitled to 28 days paid leave per year, in the US you are legally entitled to zero days paid leave, same with parental leave, a woman giving birth is legally entitled to no days off, of course most people do get paid time off, but often it's not much, in a lot of cases you'll need to work 3 or 4 years before getting 10 days and if you're sick that'll come out of those days
