| There was *NOT* significantly 'more income PER PERSON'... the term you are searching for is "per FAMILY". |
No the term that I am accurately using is per person, your apparently arguing per employee. If more people work, for about the same amount of money, income per person goes up. Income per family probably would also go up (unless families shrink, which they did but not enough), income per employee stays the same.
But that wasn't the case since average income per worker went up (so the other two went up even more). (Income includes but does not equal wages).
