One of my committee members is only a year older than me and will go up for tenure next year. She has a 2 month old baby and is looking at houses with her husband, also an academic. We live in an incredibly expensive city, as I mentioned before. A friend took a TT job in a mid-sized city two years ago and had a baby last year. Neither she nor her husband make a fortune, but they bought a house and have their kid. Somehow dual-income families in much lower wage brackets manage to have kids all the time; it only seems to be academics who require certain salaries to deal with the sacrifices of child rearing.
