This guy opens up a pack of Lays potato chips and finds five chips and some crumbs in the packet. He seems to be blaming Lays for this, but fails to take account of the fact that in order for Lays not to reduce the number of chips it puts in the packet, it would need to lift the price of a packet of chips. Consumers don’t like rising prices.
Reduce the value of the money, and producers will reduce the value (quality/quantity) of product it exchanges for it.
Lays are not the only ones doing it.
