My 26 year old nephew graduated an Electrical Engineering degree. He specialized in computer board layout. He spent four years working with his grandfather running an ocean going tug business before starting school. After graduation last spring he went back to the shipyard. He was installing the electronics and sensors needed for the new main engines being installed in a tug. The experience installing sensors was a plus in him getting hired to install and maintain sensors for a gas pipeline. $20000 moving allowance and one year rent paid apartment with the promise of six figure salary after a year.
Mt son manages a law department that finalizes purchase contracts for natural gas co-generation units. Right now there is good money in natural gas.
When the oil runs out we will go back to a labor intensive economy. Teamsters and veterinarians for all those horses we will need to pull plows and haul wagons. Sailors for clipper ships. Lumber jacks to chop trees.
My dad grew up on a farm without electricity. He spent his teen years plowing with a mule. He remembers the Great Depression as the "good old days". If we can keep enough electricity for refrigeration and internet along with antibiotics and anesthetics a slower pace of life might be welcome. Now get of my lawn.
