To be precise they want equality only in those workplaces that (most of the time) related to some not very physical or exhausting activities that even can be enjoyable in a sense (so they often reference IT in that regard, but never mining and so on)
I haven't read all the replies, so this is aimed at the original post. Firstly you sound a little immature, and secondly you've made some mega sweeping generalisations about women. Perhaps the women you're dating expect you to pay / do everything for them, the majority aren't like that - you need to widen your net! I'm in a long term relationship and we've always took it in turns to pay for meals / nights out.
There are always going to be differences though, we'll never truly achieve equality, that's biology.
