Wouldn't that affect, for instance, eBay sellers who need to ship their goods? You'd need to bump parcel mail up in cost in order to stop people using that instead. I've got small items from fricking China for less than $5 total including shipping!

Just set a 5 dollar rate for standard envelopes and slide everything else that was previously less that 5 dollars up a bit. Things that were previously 10 dollars or more would stay the same.

People who are running businesses that involve sending legitimate mail cheaply will just have to start collecting larger shipping fees. It needn't affect anyone shipping anything but small things.
