This whole discussion of jars reminded me of a truly epic MPP. This is from back in the 1970s or 80s when recycling was starting to come into fashion in the West. The Soviet Union started some recycling initiatives in response.
Now, the Soviet economy was largely run on 5 year plans made at the national level in Moscow. Didn't matter whether people wanted more or less of something, it was in the plan, so the plan would be followed. There were always frequent shortages of consumer goods because heavy industry was favored by the national government.
And then there was this one product, a soup that came in recyclable glass jars. There was NEVER any shortage of this soup because it was so vile in taste that, despite having nothing else to spend their money on, the Soviets preferred to do without rather than eat this soup.
One enterprising fellow in Kiev realized that the price for the soup had been marked down to BELOW the recycle value of the jars the soup came in. Being Mustachian entrepreneurs, you immediately realized that this is both a market opportunity and an chance to get unwanted goods recycled into something else.
So, our entrepreneur went all over Kiev and bought every single jar of that soup available for sale. He poured the contents down the drain and took the empties to cash in at the recycling center.
He was arrested, tried, convicted and imprisoned for being an Enemy of the Soviet Union.
Sorry, no happy ending. It was a true MPP.
