I disagree, there are PLENTY of people in finance (city of London) who are only in it for the money.
Of course you are 100% right here, so let me clarify a bit what I exactly tried to say. Having a job purely for the money is fine. Preparing yourself well for such a job by doing the right things during college (networking, extra-curricular activities, getting good grades, etc) is also fine, even strongly advisable I'd say. But choosing a degree purely for the money you might make after graduation is quite another thing. 1) You're not earning that money yet so I think it would be less motivating than working for the money and actually earning it already. 2) After your degree, you'll still have to get into your chosen field of money making, which is very competitive. This might also negatively influence your motivation, or least cause extra stress (although some people thrive on this kind of competition).
Adding my other points to this (i.e. that your exact degree doesn't necessarily influence your odds at getting into those fields that much), I'd advise choosing a degree you are actually thematically interested in. This will make it a lot easier to do well grade-wise, giving you better odds at getting a competitive well-earning job (if after graduating that's still what you want), and along the way you'll be more likely to find "back-up plans" that you actually care about, preventing you from being stuck with a degree you don't care about in case you don't succeed in getting your top job or you discover along the way that money isn't your top priority after all.
Adding to what JakeBrodskyPE wrote, this will help you become well rounded (which in turn will probably help during interviews, "I just want to earn heaps of money" might get repetitive as an answer to questions about your motivation for various decisions in your life).
Note: my advise applies to career tracks like strategy consulting and investment banking, for which your exact degree doesn't matter that much. If you plan on making money by being a doctor or lawyer, then obviously you do need to choose your degree accordingly.
