Housework - feminism's uncrossed frontier

According to a recent NBER survey of women and men in Europe and the US housework is divided equally (give or take ten minutes) between the sexes!!

Researcher Philippe Wiel says that the reason women feel they have less spare time than men is because they sleep more??

This US/Euro information differs from a 2005 time-use survey that showed that Canadian women did on average 4.3 hrs/day of unpaid household work, versus 2.5 hrs/day for men

Questions:

• Who the heck is America's "National Bureau of Economic Research" and why do they scare me?
• Could the recent NBER survey be a retaliation to an earlier study in the UK that said employed women living with their employed partner actually spend more time doing housework than single women?
• If men shared housework equally would they build a robot to perform housework for them? Like a robot that could pour you a cuppa and even wash the cup afterwards (video here)
• Where's Roll-Oh (the 1940 World Fair robot ) today? 67 years later and all I got was a robot vacuum!
