My late husband's first wife was also a SAHM for almost 30 years. When he left her (they were both age 50), she didn't really need the money as he gave her just about everything (and her mom had money), but she got a clerical type job-- she had no skills, not even rudimentary computer skills (this was almost 20 years ago). She is a very hard worker, extremely reliable, meticulous, and organized. She has moved up in the organization, and soon will be there 20 years.
