I have a BSLA and an MLA and am glad I did it. It made sense at the time (no one was hiring LA’s in the early 90’s either) and the MLA program (and school) had strengths that differed from my undergrad program. And while the cost of tuition has gone up considerably, there are still ways to pay for it (scholarships, assistantships) and ways to reduce cost (in-state vs. out of state). If you are just graduating and seriously considering grad school (regardless of degree you plan to pursue), now is a better time to do it than 5-10 years from now when you may have other obligations.
