Which is more in demand computer science or business administration major in marketing, economics or finance?

I think a BA in marketing, economics or finance will offer a much brighter future. It won't be too long before almost all computer science/programming jobs go offshore to countries with low wage scales. Probably half of those jobs are already gone. Most companies don't want "outsiders" going through their financial records or dealing directly with their customers which is why marketing or finance should be more secure and pay more. It will be a big help to become familiar with computer science so you understand whats going on there but you don't need to know how to do it yourself.
