Which would mean we should have up to something like 11,000 representatives given our current population. Clearly something is wrong when the average representative:constituent ratio is 1:700,000! It was originally 1:34,000.
11K is perhaps far too many to be manageable, but 435 is clearly far too few.
Edit: the 14th amendment may have changed this math before the 1911 Apportionment bill fixed it at 435, but 1:700K is still far too high.
