They do not need to care about poor people, and poor people should not be considering buying ncoins, better buy yourself some food, farm adena ingame and with soe tricks and when you live in a poor country where dollar is strong you can even buy bread for your whole familly for adena using some illegal tricks :]
If 10 out of 1000 players spend cash on Ncoins, 1 of them is rich and crazy spending 1000$+ month (in my clan consisiting 40 ppl there are minimum4 persons like that) they have enough cash to not care about the rest. Rest of players is just here as a cannon fodder to vips so they dont get bored and quit. Sad but true
