i dun know, but i thought, its better for the poor/oppressed to
provide hope themselves rather than plainly dependent on higher
beings. E.g. if they are oppressed => civil revolution like the
french revolution in Les Mis, etc...if you are poor, you struggle
and work yourself up to earn more money through education or sheer
hardworking and diligence and wanting to learn...etc.. 
if you are rich/better off, you can provide hope yourself too, like
do good to your people, volunteer, find meaning in life! cuz seeing
other people smiles/happy can also make you happy etc...and also
you can still pass on the riches to your family and children even
if you cannot used them all...and finally, there is an aspiration
that once you retire you have enough money to tour, enjoy your
later days, play golf, etc.
