The worst one, VHS and DVD movie rentals, having declined 89%, is no big surprise. Some of the others were.

Most of them you can see leveraged out by the shift to internet purchasing.

The only one I didn't understand was "Telecommunications workers" and exactly what that job actually entails, and why it is declining. If it's telephone service for "land-line" telephones, it's obviously because of the near-complete shift to cel phones, and most no longer have regular home phones, mostly just businesses. I'm not even sure regular pay phones still exist!
