First off, I have only seen the seven episodic films in the Star Wars franchise. I am aware of vast amounts of other canon and non-canon sources available. Much of the fun I have on this Stack Exchange site is reading the about some of these questions.
From reading here and following links to Wikipedia or Wookiepedia I have seen that once the events of Episode I to III are completed, the Empire switched from clones to regular humans prior to the events of Episode IV. This system seems to be in place through Episode VI. When we get to Episode VII humans are still being used.
From what I understand from the troops in Episodes IV - VI the humans are recruited, conscripted, or volunteer for service in the Empire (hence Luke mentioning wanting to go to the Academy). This would mean they some (if not many) Storm Troopers have a family of sorts. However, by the events of Episode VII it seems that the First Order is stealing/kidnapping (?) children to train them to be soldiers (Finn's comments on the matter suggest this).
So, to get to my question, I assume that clones (I-III) and kidnapped children (VII) would probably not need to be paid. The recruits/volunteers from Episodes IV-VI would be the most likely to be paid/rewarded. As we see with armies here on Earth, a solider is paid even when drafted (formal armies like the US anyway). I would think there is something similar in place for the Empire or there would be no talk of an Academy or recruits, the Empire would just conscript their soldiers. Do we see any instances of Storm Troopers being paid/rewarded for their service?
G canon is preferred, T/C canon is acceptable, and S canon only if necessary.
