Your view is that of a dedicated capitalist who sees workers as tools for business and nothing more. The reality is that society needs children. Look at Japan where due to the things you mention the birth rate is very low. It's a huge problem for them because and their population is set to fall by 30m in the next 40 years.
More over most people do want children at some point in their lives. Most people are supposed to make the rules (democracy) so companies are going to have to respect that and make allowances for them.
Of course the rules should apply equally to both genders. You could argue that people who don't have kids should get more time off, or that people who do have kids should get some benefits because the burden they accept is beneficial to society and as we can see in Japan society needs to encourage that behaviour. Society wants well brought up kids too so making parents choose between work and their offspring isn't desirable.
How about people like you get a tax break, on the condition that in 30 years time you can't see any doctor under the age of 55?
