We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I find the notion of forced diversity inane, insane, repulsive, and disruptive.
Things in that graph that surprise me - Social Sciences? - Oh wait I know who those guys are... Never mind.
Biology Biomedical - well done ladies - that's a stronger showing than I'd have thought.
The rest doesn't surprise me at all.
It's not so much that men are over-represented in engineering, it's more that EVERYONE is over represented across the board.
Assuming one can trust government figures - Labor and Industry says only 40% of jobs "NEED" a degree (which is not the same thing as the hiring agent requiring it) and 60% of the work force have degrees - which means 20% of those got them for no particular reason. If they'd in fact gotten a nice well rounded education - the kind you could get 30 or 40 years ago (or earlier), then I say it wasn't a waste. Today? With all the grade inflation and cheating - nope just a big money pump, generating wage slaves for life.
It is related to grant inequality. About 80%-90% of federal grants for schools go to women and minorities. If you are a white male you don't get them. Women and minorities are encoraged and "paid" to go to school so the next hurdle they face is what to take. Often Most aren't serious students so they look for something easy, no math, no science. This set of facts explains the chart.
