It's amazing to see that long stable time from the 1930s to nearly the 1960s, as inflation slowly dropped the cost of postage.

Can't argue but I would imagine labor costs consume most of the increases - certainly over the last 10 years, probably the last 30.

It's certainly would make sense, as that and fuel and compliance are some of the major increases for similar businesses, I imagine.
