My lovely MIL did a superb job of training her four sons (and daughter) to help around the house, her theory being that she wasn't letting them escape into the world as selfish little toerags with no idea of how to look after themselves or their future families... or she'd be stuck with them underfoot all her days! They are all extremely capable and not house-work shy at all. So a parent certainly has some influence over how their kids turn out.
I think there is still a lot of lingering 'traditional' roles though. Man works all day while little wifey stays at home cooking and cleaning and childrearing.
As there are a lot of people still alive who lived and perpetuated that sterotype it is not really any wonder that it hasn't been done away with yet. These things take time to die out and there are probably a fair few men who still view this gender role business as an excuse to be lazy and selfish - maybe not even consciously, but somewhere in their brain they may still believe women do domestic stuff, not them.
Though of course there are just lazy, entitled little arses in the world too who only really care about themselves - both male and female.
DH's first wife was just such a woman - he worked all day in a high stress job and then came home, cooked dinner, did laundry and cleaning, put her two kids (school age, so she wasn't minding them all day) to bed - while she went shopping all day or sat on the sofa watching telly. DHs sister and sister-in-laws all hated her and thought DH was a giant mug... which of course he was.
He is still very well-trained though, and I sometimes have to stop him from absentmindedly doing more than his fair share. Sometimes I have to go and turn the football game on and gently steer him away from the washing up before he gets the hint.
I confess I feel very lucky to have such a good teamworker as a husband, and I'm sorry that other ladies are still having a hard time trying to get some equal housework divisions in their homes. I am sure that the reason so many women marry these chore-dodgers is because there aren't enough good teamworkers to go 'round.
I know that in my early twenties I lived with just such a guy - I didn't like his slobby entitled attitude and frequently tried to 're-educate' him about housework not being done by fairies. But the final straw came and I left him after he had the nerve to scream at me because there were no clean mugs to put his tea in.
I told him that they were all where HE had left them... scattered around the house with his tea dregs in. That stopped him for a moment before he retorted that he'd been at work all day and I'd been at home, so I could have washed them up! Um, your tea mugs buddy, not mine. Also, yes, I was at home all day - but working on an important essay for my degree. Rather more important than his blinkin' mugs. Stupid twunt. I pity whoever ended up with him as I think he was a lost cause.
