hogwash. i made 200k last year with an 8th grade education. this year i taught myself robotics. computer vision, c++, control theory, kinematics you name it i learned it. the whole college teaches you how to think is the greatest myth in the history of man. you would have learned how to think if you took the same time and self studied mechanical engineering. the only thing college did for you was organize all the connected sub disciplines for you. yeah that was the hardest part for me but because i live very low maintenance and low debt lifestyle i could take my time and peruse college syllabus for mechatronics, mechanical engineering, calculus, c++ etc. you already know how to think. you learned a whole language without books when you were 3 years old.
