"Economics is a social science that studies the production, distribution, trade and consumption of goods and services."\n\nPeople are different and do things differently. People also engage in debates be it economical, religious or scientific because we all believe what we know "is right" and the other person "is wrong".\n\nAny subject that's attached deeply to our culture, be it politics, religion or economics will usually have huge debates surrounding it.\n\nHope this helps :)
