It is unfortunitely a well documented fact that plugs get wired backwards sometimes. That is the cause of some electrical house fires when certain critical equipment gets plugged in. Can you say POP !!!
When I bought my current house, the inspector I hired found three light switches wired wrong.
In my old house I had problems with the AC/heat pump. It would blow the breaker once a month. The repair person I hired found that the control box for the heating system was wired wrong by whoever installed it.
The problem could be there for years and never be found. Most things don't need the correct polarity (anything with a 2 prong plug). Even grounded plugs don't necessarily need the correct polarity.
Some audio power cord makers do make reverse polarity power cords. They do have their uses for altering the sound. A friend made his subwoofer more lean and tight with a reverse cord.
