What is the worth of PhD?

I am in the second year of my PhD program in sports management and just weighing my career options. Before PhD, I was sure that I’d do teaching in business schools, but lately, I am having second thoughts.

See, PhD is highly valuable in the academic and research world, but will it benefit me if I choose a different direction, such as something in marketing, sales or merchandising? If it won’t benefit me then should I just drop out and save all the money and the tensions with it? I mean what will be the worth of PhD in those fields?
