I won't accept "it's harder for women in business" because it is impossible to actually demonstrate and it devolves into a pissing contest about who has a greater frequency of unpleasant experiences with coworkers, partners and clients.

It is also impossible to balance that against reasons it is easier for the genders. How often did Heidi have an easier time being trusted or otherwise "invited in" because of being an attractive woman? No one can really claim to know who has it easier at the end of the day.

What is true is that it is different.
