  We show that the observed relationship between the fraction of low-mass X-ray
binaries (LMXBs) found in globular clusters (GCs) and the GC-specific frequency
for early-type galaxies is consistent with an LMXB formation model in which the
field population of LMXBs is formed in situ via primordial binary formation.
The suggestion that a significant fraction of the field LMXB population in
early-type galaxies was formed in GCs is not required by the data. Finally, we
discuss observational studies that will test this model more thoroughly.
