When I talk to a few people who are making good money its because they got into a growing field.
I heard nanotechnology is growing so i'm going to look into that a little bit more too
Keep in mind that "growing fast" does not mean everybody in the field is rolling around in gigantic piles of money. It means that people are getting hired.
I don't really have much to contribute beyond what's been said above. But I'll reiterate something:
You're talking about getting a PhD as a way to make a lot of money? Get real. Yes, having a PhD (in just about any field) will give you good job options, but is the desire to make $100k some day really going to motivate you through 8-10 years of work? Repeat that phrase in your head: Eight to ten YEARS. If you're not doing something you love, you'll give up (and as Wood mentioned, probably before you even finish your undergrad, much less before you start doing actual work). Considering one of the options your considering is to "not even go to college at all" (and do certificate programs), I don't think your heart's in this enough to even finish a (difficult) BS, much less even think about a PhD.
That said, I've known plenty of people who chose not to go on in academia, and instead entered the real world. A few things I've learned:
- Everyone I knew who went into computers (CS/CIS/MIS/etc.) is now fighting to get jobs they hate. The (delicious) irony is that they all chose those majors because they were supposedly fast tracks to good money.
- If you can pull off a math major, there's a lot of good tracks into actuarial and investment banking type jobs which pay well.
- Chemical Engineering and Electrical Engineering both seem to have excellent job placement. Every electrical engineer I know did well after graduation.
- People go into physics because they like it, not because it pays well. Physicists do well in the job market, but you're better off just doing EE or ME instead if job prospects are all you're interested in.
- Most importantly: All of the majors I've listed above are known for having high attrition rates amongst people who aren't really interested in them. You're not going to put up with 4 years of physics/EE/whatever homework if you're, you know, not interested in the subject.
Now, if I can be rude for a minute - to be honest you sound like a lazy person who wants to get the most he can for as little work as possible. In this thread you've listed off a half-dozen or so careers which people typically dedicate their whole lives to, and you seemingly want people on bluelight to tell you which is the easiest, or at least has the highest pay/work ratio.
Now, think really hard about what that says about you and how solid your prospects in
any field are.
