Law is glutted, and only the upper part of the strata is safe. Engineering was highly in demand 5 years ago, but now the demand moved from very high to moderately above average. Programmers I talked to said the software revolution happened a decade ago, and now it's very competitive.
Nursing is in very high demand right now; it's said that most people in the program have an easy time finding a well-paying job. But will it be like engineering in that 5 years from now, millions of extra people enter nursing due to the hearsay and it's no longer in demand.
