it's definitely not the only industry where women make more than men. Also female leads don't get filthy rich by any means. The very top net worth porn actress is likely jenna jameson with something like a $30MM net worth. Compare that to the top paid hollywood actress jessica alba who has $350MM net worth. Also consider that porn actresses pay distribution is extremely top heavy. I think worldwide known actresses like sasha grey only have a couple million. To put that in perspective many white collar workers retire with a similar net worth as sasha grey who is a worldwide re-known porn actress and her videos probably get stream tens of thousands of times every since day.
