Is to rely so heavily on letters to her "Dear Prudence" pseudonym. Well, of COURSE these people are going to have problems raising a child on their own since they feel they have to write to a total stranger for advice.

Yoffe completely fails to note that there are (at least) two types of single parents. There are those who are educated, affluent and emotionally stable who want to have a child on their own. And there are the lower-class, under-educated and under-achieving whom a child just happens to. Lumping the two together makes as much sense as just looking at the nationwide gas mileage figures when trying to determine the numbers for each individual car.
