If you like to do business economically you can study economics, but there are many successful entrepreneurs who do not go to universities that they are rich from their own experience as well as their bravery so the need to study economics is not necessary.
right I agree with you in my country there are also many successful entrepreneurs who have never felt at college. there are even among those whose education is only up to junior high school. Strong experience and determination is the key to being successful. but studying economics at university is also a good thing so we can study the economy very well. and when it has passed we can apply it in the community.
