they breed to preserve their family name.. deaths are high there so they have to breed quicker.. but in comparison to the US and other first world countries.. we dont want to breed til later now thx to wanting money.. Plus our old are getting older.. thx to medicine.. so now we have a growing population that is dying slower but costing us more.

Children are work hands, not enough education to know better, not much else to do, social customs, and a low average life-span requires a good birth rate to replace the dead.
Many don't have jobs and have free time to have sex without the funds to purchase condoms.
