Not sure what the point is.

 The proposed tax changes target small businesses, not women.  Naturally many small businesses are owned by women.  But none of the proposed  changes target women specifically.  And the authors did not address any of specific details of the proposed changes.  It was simply a lament about the challenges women face in running a small business, which dont seem to be much different than the challenges women face holding down any job.  So what's the point?
