Umbrella Socialism

Umbrella socialism - It is a common illusion that umbrellas are not exclusively personal belongings but socially-owned items that should be shared by anyone else, not just by the supposed owners, contributing to radically reducing a sense of guilt that using others' without any permission is a clear case of theft.

"Hey, that's not your umbrella, is it? I saw that in the umbrella stand at the cafe, when we went in"
"I steal theirs, as they steal mine. That's Umbrella Socialism".
