Inflation is here, now. I wish I could remember the name of it, but there is a website out there devoted to documenting how various products are shrinking in size, so they can be sold for the same price, instead of selling the same quantity for a higher price. Toilet paper rolls (measured end to end of the cardboard tube) are a quarter to a half inch shorter now, and fewer sheets are put onto each roll. Half gallons of ice cream are no longer half gallons.
Eventually (probably in the near future), it's no longer going to be possible to hide inflation by shrinking product size.
If you and I have noticed the shrinkage, I'm sure others have too. The rub is that the Consumer Price Index doesn't reflect changes in food prices. Ditto energy. They say they're too variable. They think we're stupid.
