Re: In the current environment, women are too much of a business risk..
My sister did exactly this. Fought tooth an nail to get into an extremely specialised field, studied to get a PHD over 5 years, went into the work force for 2 years, had a kid, decided she liked being a stay at home mum better, had a second kid, waited for her husband to pay off her student debts, then divorced him and took most of his stuff, and hasn't worked since.
Sadly, this is an all too common tale nowadays. Modern society has fostered a breathtaking level of entitlement among women which, when combined with the ever present undercurrent of misandry, makes it very easy for large swathes of the "fairer" sex to game the system to their advantage.
