I don Not beleive that is a serious question but here are some possibilities,
a) HKBH decided they should be poor (see Chovos Halevovos Shaar Habitochon, so no matter what they do they will fail.
b) They have ability but are simply lazy and ok with being poor as long as they can make ends meet.
c) They are lazy and expect the government to help them.
d) They went to school and received an education that was more about indoctrination then preparation for the workforce.
e) They were trained in a field that changed leaving them flat-footed.
f) They were factory workers whose jobs were outsourced.
.
g) They worked in an industry that was targeted by “activists” until they went bankrupt causing employees to lose their jobs i.e drug companies, weapons manufacturers.
h) they lived in countries that feel for socialism promise causing work or pensions to dry up examples are Greece or Venezuela.
Of course there are many more possible answers to your query but that is a very very partial list which is the very real reason millions of people around the world are poor.
