(correction please) It would be better for family life if people worked 4 days a week instead of 5

I partly agree with this statement. In my opinion, it depends on the family. In think if the family is a united family, that they like to organize events between themselves and don’t need the money, they can afford to work less. By contrast, a family that has economic problems, I think they would want to work as much as possible to pay the bills. The problem isn’t in working five days, the problem is that people can’t manage the time well. I think there is time for everything and if we are organized. have a good organization, We can work, be with family and go out with friends. There are also families that have many problems between them, so I guess that for these families they don’t mind working more and seeing each other less.

Wow, you are at a really high level in English (I wish my Spanish was even half as good as this). The corrections above are small but just make it flow a little better and sound more natural. Really great effort!
