The last time we had a two cent increase, the cost of mailing half the stuff I mail doubled. (Size, thickness, and stiffness, which never cost anything extra do now, and not in any way that has gotten any publicity that I've seen.)

First size, weight and thickness rules regarding mail came into being about 300 years ago.

What I think you are having a problem with are the thickness standards for letter mail. They are of somewhat recent vintage ~ I wrote the first ones.

What you need to do is quit stuffing all that extra stuff in the envelopes, particularly if it's advertising. Send that at Standard Rate rather than at a marked up First Class Mail rate.
