In my opinion there are a big amount of jobs which are not really necessary and just offered to increase the service level or to show personal presence. Here are a few examples:
There are always three people at a exit of a construction site taking care that nobody gets into or get hit by a truck.
10 people are working at a gas station.
Guards standing at the beginning of the escalator telling you to stand left and use the handrail.
I just can’t understand why they don’t need to save money. The japanese economy is not the beat recently.
Who knows what’s wrong at this picture?
