Employment

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?
