I think we could actually use more liberal arts types. Unfortunately the only places teaching liberal arts seems to be Hillsdale College and a few others.
Most engineers seem to have had this natural tendency to like to take things apart to see what makes them work, or creatively build or fix things using a combination of materials no one ever thought of using.
Several years ago the Wall Street Journal had an article relating among other things - how challenging engineering is as a discipline (one must have the mindset, mathematical competency, etc) as manufacturing has moved overseas so moved many entry-level engineering jobs, and many young people who had the aptitude to become an engineer, avoided it because they did not want to endure the difficult course of study. Today’s resurgence of manufacturing in middle America should bring more entry level jobs.
As far as liberal arts - they need to be important to science, math, engineering majors. Just like some challenging science and math should be an important part of a liberal arts education. The issue is what is termed Liberal Arts today seems less education and more leftist indoctrination.
