Who here thinks the IT industry is going to be HOT once again??
I doubt it.
During the dot-com era when salaries were highest, the whole internet and computer scene was relatively new to the masses. Because of the relative newness of IT at the time, there was a shortage of qualified employees which led to higher salaries.
Now that time has passed, qualified employees are somewhat easier to find as people saw this as a "hot" sector and upgraded their skills to follow suit. With a larger pool of employees comes a drop in average salary as there is more competition amongst similarly qualified employees who are willing to work for less and less money respectively.
I'd go for the finance degree myself, as it will be safer in the long run.
