At my uni (swinburne), there are heaps of people doing marketing. From the people I have spoken to, I think a lot are doing it for the wrong reasons. It seems like they want to have a 'real job' and go to work in a suit and make decent money. However, after the introductory maths unit of the business degree, they shit brix and look for any major that doesnt involve maths.
Obviously this doesnt apply to people like stazi and others who have a genuine passion for marketing, but I worry about people who may be doing it for the wrong reasons. At least with an Accounting degree you are virtually guaranteed a job as an accountant somewhere. If you have mediocre grades and no passion for marketing, theres hardly any chance at getting a proper marketing job and your likely to end up in telemarketing etc and not use your degree.
