I’ve got yet another doc (not sure of the source-- was emailed to me as an
Offical ‘standard Lego FAQ’ sorta thing) that reports:
“The precision molds are made at two LEGO factories in Germany and
Switzerland. They are precise to five-thousandths of a millimeter.”

First, what ABS can allow moulding to is different than what the company
targets. Precision costs money. Decrease the tolerance, and you increase the
cost, because more rejects are made.
Also, the mold tolerance is different than the part tolerance. My understanding
is that the parts will have a greater variance than the variance of the molds
themselves, since the parts expand, contract, are expended by the removal robot
etc.
But that all said, I think I have to agree, the PERCEPTION of quality is
important here. Perceived quality is why people pay extra for Japanese or
European cars. Maybe Korean or American cars are just as good in terms of
reliability. But even the perception of better quality is enough to justify
buying a Toyota or a Honda over say...a Chrysler.
I don’t think our perception as nitpicking enthusiasts matters, but if this
perception slips to the end customer, who knows what will happen?
