We can only hope that one day soon there'll be no reason to single out women as a specific category when we look at up-and-comers in the world of business.

Meanwhile, many studies maintain that women have significantly reduced access to capital and encounter less favorable loan rates. And don't get us started on the discrepancies in compensation between men and women performing equal work.
