Planned obsolescence means that the thigh high socks degrade quickly, forcing consumers to purchase new pairs more often than they really need too. The fabrics are now less resistant to excessive sweat, moisture, and oils. Shrinkflation also means you get less sock for the same amount of money, increasing the margins for the sock megacorporations. Additionally, the missing sock ghost (who routinely steals socks from a pairs leaving victims with just the one) has struck a deal with Big Programmer Socks to increase the number of lost sock pairs over time in exchange for a large share of the profits.

Im good at the economy. If you turn off the electricity you have an extra $300 for your Thigh-high socks
