No it is true especially regarding a physics degree from a decent university. Why ? Because physics is about studying, applying mathematics to and manipulating the physical world.
You have a better knowledge of the physical world, manipulating and predicting the physical world. and you are more knowledgeable about almost everything as a result.
I will concede that athletics and predicting and manipulating people are not things physicists are good at.
You are very, very wrong. Maybe 70 years ago a person could switch between specializations in STEM, but that is impossible to do today because of the depth of knowledge required in a STEM specialization. Even worse, most experienced STEM workers are actually linked to a sub-specialization today and can’t even qualify for employment in their general area of specialization.
Thirty years ago I would go to an international meeting in my area of specialization and meet with the 80 key people in the field. Today I go to the same meeting and there are now over 3000 people in that area of specialization. Within that specialty there are maybe 20 areas of sub-specialization. Virtually all of these people are employed with soft money.
Two things about a physics degree:
1) most importantly,it is a certificate of intelligence.
2) additionally, the math required combined with that certified intelligence makes you a shoo-in for a high-paying career in finance, if that’s the direction you want to take.
