What is the role of marketing to the society? Does it help decreasing the unemployment?

Well said and explained by Mohammad Abdelqader Alfar.

Marketing can inform and educate consumers about available goods and services. It can also help them make decisions and choices when it comes to purchasing a good or a service. As for unemployment, the marketing sector's share of workforce is continuously growing globally which implies that the sector can actually help decrease unemployment by continuously offering new jobs.
