Why Stamps Keep Going Up

The other day I was scanning through the Boston Globe and I came across a full page ad for the US Post Office.  Why?  Is it suddenly ad worthy to say "Hey, we're the Post Office and we still deliver your mail"?  This is just one more example out of many of why the government wastes our money and why we need to stand up and say no when they keep asking for more of our money.  There is no need for a full page ad in the Bosten Globe from the Post Office.
