Its just personal preference.

If you are single and/or a "lady's man", have very little ties to family, relatively low expenses, etc, this is a dream job.

If you have a family, wife, and want to build/preserve these, have fairly high overhead, then it is a lousy job.

Apparently its not so bad, because people are still signing up in droves to do this. The lines out all the doors will always be cattle call's of more applicants than positions.
