Will a minor in business matter to employers?

In about three years, I’ll be graduating from the University of South Carolina with a BA in Psychology and a minor in Business Administration. My long-term plan is to get my MBA and work in something like marketing, advertising, PR, or human resuorces. However, good MBA programs require work experience, so I need to start working my way up the corporate ladder. I know it’s possible to get a job in maketing, for example, with a BA in psychology, but will the business administration minor/classes look better on my resume or will it really not matter?

I plan on living in Rock Hill, SC and working in Charlotte, NC where jobs in business or more available. Does this sound like a realistic goal with the degree I’m seeking or does it sound like wishful thinking?
