It's one of the most difficult problems there is. As you rightly note, it's not money alone. What exactly 'brings on' motivation is not known - and whatever it may be, it varies from individual to individual.
Many 'monied' and otherwise privileged individuals get 'spoilt' by the ease with which things fall into their laps - they never make the effort to overcome any difficulties or barriers.
Many 'poor' individuals (who may otherwise have many other worthy characteristics and qualities) get frustrated by the difficulties they have to face - and once they get frustrated, they also take the position that it's not worth making the effort at all.
How to overcome these different 'demotivators'? All teachers must have seen sizable numbers of such cases at both ends.
Well, we do know that an example of someone who is admired by the demotivated person can help - but it is usually counterproductive to say "Be more like so and so".
