First off, forget what your parents want you to do, you're the one who has to work in the career that you choose.
Second, forget about the money. Sure, it can be a set back, but would you rather have a job you hate where you make lots of money, or a job you love where you don't get as much? What's more important to you? (Also...maybe when you get married your husband will have a high paying job :) or even if he doesn't, his income will help).
Besides, there aren't many jobs more prestigious and fulfilling than preparing kids for the rest of their life.
