Why else would we have "forever" stamps?

Did you ever wonder why the US postal service started doing "forever" stamps. I'll tell you why I think they did. If you read here you'll notice that they raised prices again. It's less of a headline now since we don't have to worry about getting those 1 cent stamps anymore. But you can count on this happening a lot more often in the future since they don't have pricing on the stamps anymore to remind us of what they cost us.
