Quoted from vid1900:
If you never get married, and never knock any broads up - you will save, on average, $280,000 per child you don't have to support to the age of 18.
Then think of the additional savings when they don't move back into the basement, as 58% of them do, after college.....
You can teach them to repair your pins and cars etc. so you don't have to when you get older. Plus, if you treat them right and educate them well, they may have a decent career and can buy you some nice things. They might choose a nice nursing home for you and even cover some of the funding shortfall.
