Well, yeah. Most people would much rather spend their time and energy taking care of their children than laboring away for someone else's profit. They may not phrase it like that, but raising children is far more self-fulfilling than working a job could ever be for most people. I imagine in most cases, people prefer tons of hard work raising a child when compared to working the easy cozy job, because at the end of the day the job is just a means to an end.
