According to all logical measures of, it is better for a child to grow up with a parent/ parents with more money and more maturity. I'm sure there's very good young parents out there, but I'm also sure that there's very good single, career women raising children.
Study after study shows that it's the two parent home that matters most. Money sure doesn't hurt, but it's two parents with one staying at home during the early years, anything else is icing on the cake.
