You get a job because you want to make money. Whether you write Java stuff for bigcorp a or bigcorp b doesn't matter, they are going to require the same skills so they are "commodity" work places. You get a job there because you love to code and would like to make money. In short, you love to work.

Now, there are a few exceptions, of course, such as Frog Creek or your dream job, where you get a job because you love to work there.
