What way can you make money after graduation?

We are studying to improve our knowledge and theory of living which will be applied to life. So, instead of groping for some ways from beginning, we'll be able to put the achievements in science into work to get the most effective result, or study to invent new prospects.

I'm learning IT, so I wish to be worked in my specialty. I hope to be able to create effective applications, high practical softwares, which are useful for life a lot.

However, today, you can see the number of students who are worked in their specialty that they have trained with is very small. Almost students have to work out of their specialty only to make money for current living. If it isn't lucky, I will probably be that as well.
