This is so funny. A couple of (terrible) examples and you've debunked the entire theory that the world is designed for men?
Ads: haha, when MEN are the ones who actually DO the mental load of thinking about what the house needs and buying it accoridngly, I'm sure ads will be aimed at them more. Just like fancy car ads ARE, in fact, mostly aimed at men.
Insurance: As I understand it, it's risk based - women are statistically less likely to write off a car (although I think I read somewhere they make claims more often - just smaller ones. I might have made that up).
AMOUNT spent on women's health - I think it's quite likely that overall, certainly on a day to day basis, women's health may well cost a bit more. Certainly, between two pregnancies and some pretty severe peri-menopause issues, I've cost the NHS more over the last 15 years than DH has. And I'm one of the lucky ones - many women I know are costing the NHS more long term becuase of the damage that childbirth and pregnancy has done to their bodies with everything from physiotherapy to surgery.
But we do know that medical research does NOT take women into account - data is not disaggregated and quite often, research consciously and specifically leaves women out because of those pesky hormones of ours. As a result, medications and treatments are designed for men, and we are learning more and more, are not necessarily fit for purpose for women (heart disease being the most famous classic example). As for the breast cancer vs prostate cancer thing - breast cancer receives a great deal of attention because of women who have fought tirelessly to raise funds and awareness. Men could (and in my opionin, should) do the same for prostate cancer.
Of course, having said all that, I'll never forget the amusing meme I saw once that said if men had to give birth, we'd have test tube babies by now!
Family law biased towards women? My ass. Men THINK this is true becuase they don't understand why their ex wives should get the house but that's because they're convinced that if they've been working while their wife hasb een at home, it's THEIR money. In reality, in most cases, women continue to be financially disadvantaged in divorce, particularly if they continue to be the main carers and have taken significant career breaks or have to continue to work around children.
As for job opportunities. I know, it's a shock we want equal opportunities. As for doors etc, most women I know don't particualrly care. I like it myself - but more becuase i see it as similar to driving on the left and overtaking on the right - it allows us to all physically move through the world without bashing into each other. But I'll DEFINITELY take equal pay over Jack in Accounts holding the door open for me.
Needless to say, there are 50000 other examples of where the default is male (as already stated - Invisible women is great for this) - from crash test dummies based on the average man that mean women are more likely to be killed or injured badly in car accidents, to the size of a piano's keys to the way aid is provided to families in warzones.
