clearly, it's a matter of degree, so the number I post here are obviously NOT the case...but they make the devil's advocate's point....

What if there were 100,000 x's
and only 1 y and 1 z.

AA would be smart to make 100000 people happy at the expense of y and z.

And I have to think that AA knows the numbers....

and while it's clearly not as easy as 100k versus 1 and 1, the numbers must make sense.
