But I won't conceded that what the US calls "Maternity Leave" is not in fact it by any modern standard of the term, it is nothing more than a job assurance program that even according to you only reaches 60% of people. And out of them few can afford it (and even them not for its full duration).
A handful of US states offer legitimate Maternity Leave and they should be congratulated for that. The federal government should be ashamed, FMLA is pathetic, and their inaction lets people (both parents & children) down daily.
To be honest I'm not exactly sure what point you're trying to make. That the US is awesome? That maternity leave is fine? That you just want to be "right?" If it is the first two points then we'll never reach consensus and if it is the last point then this is all a waste of time.
