Home ec
"Part of the problem is that in the 1970s, Home Economics was improperly viewed as nothing more than 'stitching and stirring,' and some of the feminists of the time led the crusade to eliminate Home Economics from school curricula entirely. They did not totally succeed, for which I am grateful."
I don't mean to stir the pot (pun fully intended!), but I can see the view of the feminists. Home ec. was once a girls class. Indeed, I knew one guy who was in high school in the 70s who took home ec. for that reason. Back in my parent's generation, girls took it because they'd get married and keep house. Boys took shop because they were the ones who'd fix the house.
I wonder how many families of the 50s--a time appear to want to go back to (and no, I'm not talking styling/quality of appliances, but the supposed family values of that era)--suffered because of gender roles. I can imagine meals that were so awful they would make a 2010 Banquet TV dinner seem like Julia Child's best, and carpentry projects that fell apart from the slight vibration of the family hamster's racing wheel across the house. Just because the family was locked into "Mommy cooks, Daddy fixes things." Maybe sometimes--if they could have looked past gender roles--Daddy could have done a better job cooking, and Mommy's natural talent could put Norm Abrams to shame.
This problem aside, I do think that home ec is something that should be taught. Indeed, maybe we should go back to making it a required class--make it a year or two of "Basic Life Skills" where people learn the basics of cooking, home repair, etc, etc.
Problem is: finding the time. Classes needed for graduation are increasing. Even some elementary schools, I believe, are eliminating recess to hit the books harder. (I'd have hated that. Recess was my best subject!)
Other problem with cooking is figuring out a way around dietary limitations. One other improvement has, I think, been more flexibility in our culture for those with dietary limits (alergy, other health issues barring stuff like wheat), or ethic issues (like vegetarians).
