False dichtomy "careerist" "or" "family". Modern family can evolve to just as other relationships. It is very frightening for a child to be left at a day-care center, it would be much better if the parents could bring their children to work and have an "office" only for kids. Hire a baby-sitter and you are all set. Work and family.
Don't tell me this and that as reasons why it cant work. It works for me and my coworkers just fine.
