The fantasy they were offering is "You can have it all!" It should have been obvious that was a lie. How could anyone possibly believe that they could have all the things men get plus all the things unique to women? Of course it helps selling that fantasy if you are also deliberately blind to the downsides of men's lives - like sacrificing home and family life with 50+ hour weeks to get that advancement, or working the high paying but dangerous jobs to acquire that higher income.
