I was intrigued by the value so did some research.

I would guess the 15$/hour value was chosen to approximate an average gross salary. The annualized payment would be 31200$[1] and it seems the average annual salary was around 30359$.

Updated to 2022 values the annual gross pay would be 10033€ [3], current average annual gross salary is 20483€ [4].
