If your motivation is only money look into getting into finance (double major math/engineering/physics and finance all work well)
I'm getting more and more confused now. A PhD does not help your wage? Call me greedy, but I have dreams of doing stuff that a 60 grand wage for the rest of my life will not cut. What is the point then, of getting a PhD? Can you actually do more at least?
Are there any other paths you can take where tuition might be waived/not as expensive?
What else can you do in graduate school after an undergrad engineering degree? Can I get a PhD in economics?
I'm still really unclear about this. Can I count on spending 150k undergrad knowing that I will have a tuition waiver in graduate school?
If this were true, it would make sense for every engineer to get their PhD, so what am I missing?
Well the reason I don't want to start with chemistry is because engineering is more versatile, can't you go onto more things starting with engineering first?
