If you are not dedicated to grad school, your time as a grad student will be miserable, and there's a pretty large chance you won't finish. Getting a PhD takes a ton of work and dedication.

There are plenty of jobs for math majors (look into consulting, actuarial work, Wall St., etc) that pay good money (or at least better than 45k/yr). The advantage of having a math major is that it's clear that you know how to think and analyze. The disadvantage is that people may think you're socially retarded, so you'll have to show them otherwise.

And for whoever said half of 45k for grad students' salaries -- keep going. Most of my friends are making about 15 or 16 for the 8-9 month school year, and maybe getting 3k in summer support.
