I too was raised by my mom, but I think that when we talk about the problem with single parent families, what we are usually talking about are families that are single parent by choice (divorce, never married, etc), not single parent because one of the parents was killed (like my dad and Lesa's) or died from some natural cause. I don't doubt that I would be a different man had my dad been there to help, but my mom did a pretty good job. I got through school and college and married a nice girl and will be celebrating out 37th in March. My dad was killed on the highway (if you can call those roads in La. that) when I was only 6 and my brother was not yet 2. My mom was college educated, my dad was an engineer for Standard Oil, my aunt and uncle were also college grads, mom's mom a teacher, (as was my mom and her sister) so education counted in my family. My mom's friends were teachers, lawyers, business people, and my mom made sure that she knew what my friends and I were up to. My mom had me convinced that I was recognizable enough and that she knew enough people that I would never be able to get away with anything.
One interesting thing is that most of the parents of my school friends stayed married, and in fact of my four or five closest friends, all their parents stayed married, and all but one of my good friends from grade and highschool are still married to THEIR original spouses. My inlaws have been married for 61 yrs.
