My Daughter was born in the middle of my first year of law school. I was already in debt up to my ears. We had no medical insurance. I clearly could not afford her. Still, we managed and 8 years after I graduated from law school, I paid off all my debt, and by then had a Son as well. People are selfish when their leisure time is more important than a family. I wonder what leisure time they are talking about. I'll bet it is not playing catch with their Son or tennis with their kids, or taking the kids to the swimming pool. Those things were more fun than anything that I remember.
We "can't afford" our kids, either ... at least if you believe the statistics about how you need 1,000 sqft of house per family member, all that.
I like being with my family. We run, hike, go swimming, read books, watch movies, cook, and all that "leisure" stuff.
