Has she gone and talked to an advisor in a University? I would think she may want to take some refresher courses, but she certainly would NOT have to start over. If she gets some pre-requisites at the undergrad level, she most certainly could prove she is competent and then apply for an MA program. There would certainly be no reason to start her undergrad general education requirements over again!
I have a friend who did this actually. She had a BA in computer something or other. She was worried she would have to start over. She didn't! She needed about 5 classes in undergrad first and then went on to get her MA and did find a job in her field. Of course, for her, she didn't make as much as she would have had she been working for the 20-25 years prior, but she did ok.
While I think it is never a waste to go to college, I am also the first one to say it is never a waste to stay home and be with your children if that is what you desire.
One thing that really gets me is people who are not pro-active. I am NOT saying this about your friend, but over and over again, I see people wallowing in their "Oh, it just won't work" mentality without actually TRYING to figure out how it can be done.
I will give an example. I went for my second grad degree at a University. Towards the end I decided I really only needed the credential and not the MA as I already had another MA and CA didn't require me to get an MA in the new area as long as I already had an MA in something.
When DH told me he wanted to move out of state I started researching and found that our new state would NOT hire me in that field without a full MA in that particular area. I went back to my Univ. and met with the advisor. She told me that because the program had changed, I would have to essentially start over again. I was almost in tears.
However, I decided to take the bull by the horns and wrote a letter to the head of admissions explaining my situation and how I left the Univ. with only 2 classes and a thesis to finish up and could I please finish up those only to complete my requirements. He responded with a WRITTEN approval of my request and I was able to finish up in the next semester.
So, just because person A says no or you think so and so will not allow it, go higher up, beat down doors, get 'er done!
I could give several other examples of people who think they have hit a blocked door, only to persist and get it open.

She's 51 years old. She has a BA, in computer science, but hasn't worked in the field in nearly 30 years. Nobody is going to hire her to do computer science. If she went back to get a Masters, she would have to essentially get a bachelor's first, because it has been so long. To get a first job at 55 or so, well, I wish her luck with that, but I think she'll end up doing check out at Target if she's lucky. So sad.
