Ioannis,

You should not be surprised to hear that PhD holder is writing essays for students - being academic and being rich are, generally speaking, antonyms. Academic have to work a lot but earn very little. However they are also humans, they want to eat well, go out and etc. Essay-writing is a good source of money - well paid (if you work for a reputable company) and your academic colleague will never find out about this part of your life! :-)
