We generalize to elliptical models an argument introduced by Gould, which c
onnects the microlensing optical depth toward the Galactic bulge to the Gal
actic rotation curve. When applied to the latest value from the MACHO colla
boration for the optical depth for microlensing of bulge sources, the argum
ent implies that even a barred Galactic model cannot plausibly reconcile th
e measured values of the optical depth, the rotation curve, and the local m
ass density. Either there is a problem with the interpretation of the micro
lensing data or our line of sight to the Galactic center is highly atypical
in that it passes through a massive structure with small solid angle as se
en from the Galactic center.
