I'm a CEO who does his family's dishes as night. It keeps you grounded. It's a good message for your kids that in spite of their wealth they should clean up after themselves. It makes a connection to the millions of hard working people out there. Finally, if your wife cooks dinner (as mine does), it shows appreciation for her work and effort. I use a dishwasher (as does BillG most likely) but there is still plenty of work like pots & pans.
