Many feminists today would use the term 'equity' rather than 'equality', because reproduction is largely a female responsibility. The changes in the body, hormones, moods that this entails can never really be known by a man, and thus equality is impossible to achieve. But given that reproduction is the most important job in human society (e.g. the essence of life on earth), those responsible should be properly compensated.

Yes face it, we all have mothers. An earth with (100 females and 1 male) would be much different from one with (1 female and 100 males).

Equity becomes equality if reproduction is not an issue, when males and females live out similar lives like in Aldous Huxley's Brave New World (1931). Interestingly, in bee society there is only one reproductive female (the queen) and all worker bees are female. Hi mom!
