Hello there ,

If you want to compare between teacher-student  or medicine-doctor .. then it's not possible as they are totally dependent to each other . Without teacher , the significance of student will not exist .. similarly , without any student .. teachers are incomplete to distribute their knowledge among people .

Same reason comes for doctor and medicine .. any medicine for severe health issues must be verified/prescribed by doctor before purchasing. And without medicine , doctors can't treat patients !

Scientist and Entrepreneur are two different profiles in career prospects and both are important for the relevant fields !

Hope you undestand!
