Welders or Philosophers? Welders make more money than philosophers. We need more welders and less philosophers. — Marco Rubio, Florida Senator and presidential candidate
The problem I see here is that, just like most things in capitalistic supply and demand, when there are a lot of welders for the same amount of work they tend to get paid less.
I used to do a lot of welding, industrial, automotive, house and ship repair. A lot of the time, especially on long heavy welds, you start running on auto-pilot after a while. That gives you plenty of time to contemplate the workings of the universe.
As the world moves away from old fashioned, mostly manual labor there is more and more need for specialized training to keep the hi-tech machines running. But a lot of the work requires little thinking after initial or refresher training. Nowadays I see so many people with no problem solving skills and little inclination to even try. It is much easier to call in the next expert in the line.
Only a politician would state that thinkers are not needed by society.
