There are about 70 million single family homes. If we count all dwelling units, we're at 140 million or so.
So the average kitchen lasts 35 years by that metric, to 70 years. I suspect the 10-15 year number counts "refreshes" and not just tear-down/rebuilds. Cabinets these days don't often last 35 years without some work.
That'd get expensive quick, a lame way to spend a million dollars over the course of a lifetime.
