An anecdotal argument like this is generally unconvincing. I have a myriad of personal problems, but I can't go to a senator and say "America needs a solution to <the problem I had>", no matter how many other people have had the same problem. Where the latter fact becomes real leverage is in the data - but without the data my argument would not amount to much more than whining. Furthermore, the data needs to prove not that such leave prevents personal distress, but that it's good for America's bottom line. Unfortunately for fathers, the objective fact might be that such leave is worse for the bottom line. There's a reason workaholic cultures like Japan's bring about economic miracles, albeit along with a plethora of social issues. Economics is a huge focus of policies, for better or for worse.
