What happens after kids go to primary school in developing areas?

Well its really not that complicated.

In Kenya education for the most part is still not free let alone affordable, so even primary school graduates are at a higher standing than lets say 1st grade dropouts. In the U.S high school graduates are also at a higher socio economic level than high school dropouts and those high school graduates are more likely to pursue higher education. In Kenya secondary school is kind of like college, you have to apply, pay tuition, get accepted e.t.c..so if a child completes primary school hes 1 step closer to attending secondary school than a child who doesnt.

My great grandfather completed 5th grade and stopped but back then it was a huge accomplishment and his children (my grandfather) were able to attend university. So because my great great grandfather saw the value in education my grand father was able to become of the first kenyans to get a degree abroad. And my parents both went and got their doctotes. So giving poor children in kenya that opportunity to get an education really sets them on the right foot.

and another thing ***

I've always been an advocate for education, Kenya does not need food or any other sort of humanitarian aid, we need education. I was in kenya last summer and I saw children walking 8 miles a day, barefooted, in the hot equatorial sun and when I asked them what they wanted, I got answers like school books, pencils, books, shoes to walk to school,...it seems like everything they wanted revolved around school and truly education is the only thing that can get these children out of this corrupt system.
