What law or other is missing in your country ?
After living in France for a while and returning to my home country (America). I found there was a lack of social assistance. So i think we need to add more of social aid for education and health

Agreed. The lack of any sort of social assistance is striking when compared to europe. And yes I know its because of taxes, im not saying one is better than the other just different. I have some friends that live in berlin and I was astonished by the amount of materinity leave they get. Its like 1 year of lik 75% of normal pay, per child and can be split up any way. So you can both take off 6 months at the same time, or like switch so the mother takes the first 6 months off then the dad takes the next 6 months off. Really interesting.
