As the nations get fatter, "unskilled" physical jobs will become the skilled jobs since less people can do them.

I always hated "unskilled" when discussing physical labor jobs. How many of you can install an HVAC system, re-sod a kids park, carry things weighing 100+ lbs all day, weld, are physically fit enough to carry garbage all day, chop down and carry away trees, how many of you can literally be on your feet 10 hours a day?
Everyone can type and enter data into a computer. Everyone can plug shit into excel. In the future "unskilled" jobs will be the skilled ones as more and more people are used to office work.
