For the record, if Berkeley phoned me to demand that I return either the Philosophy degree or the MBA, I'd give up the latter -- in a heartbeat.
Yes, the MBA has allowed me to make a lot more money. I'm glad I have it.
But the Philosophy degree expanded my mind and using the thinking skills it taught me bring enjoyment to my life every single day. The MBA feeds my body, but logic and philosophy feed my soul. I don't know how you put a price on that.
If I had gone the safe route and taken "Engineering, computer science, pure or applied sciences, nursing, or business/accounting" I'd probably have shot myself by now. I've taken computer science and accounting courses to increase my understanding of my job and yes, I do pretty well at them. But I couldn't do them every day or care about them -- I'm just not that kind of animal.
I suspect that the engineers on this board feel the same way about liberal arts, and god bless them, one and all. The key is to do what suits you -- you cannot fit a square peg into a round hole and expect the peg not to eat its heart out, eventually.
I think we are all doing more or less the right thing for ourselves. Otherwise, we'd be doing something else!
