My question would be... if your family is that successful, why is the tired/exhausted thing an issue? The game is obviously still functional and the family is WAY more successful than mine is and mine don't get exhausted often.

In my mind, like real life, a couple who works that hard to get the finer things in life IS exhausted much of the time, so it makes sense... No?

I think it's legitimate in your case, you're working them a bit TOO much. Arthur has even said as much regarding working the people all the time.

Just my .02
