It’s a race between junk food vs. an actual meal. Junk food is easy and self indulgent, real food requires time and effort. It doesn’t matter that junk food is a terrible value and lacks any nutrition. The Trump people choose junk, conservatives choose Trump people because the Trump people are mathematically mandatory to maintain their caste.
I’m going to disagree with most of these comments. They don’t protect the prong so much as they protect the cord or other objects in the cords vicinity (painted surfaces, fragile surfaces, etc). The little plastic cap that covers tire stems on cars and bikes , while keeping it clean when installed, are primary to prevent chaffing issue on the inner tube whike shipped and stored; same thing with this prong shroud. They have holes in them as to not retain moisture I imagine.
Long story short, the prongs are metal and have corners. They are the strongest, “sharpest” thing in the box. The plastic isn’t protecting the prongs from us, it’s protecting us from the prongs.
