Adding to what Sniper said above....after colonialization there was a huge mess. Countries in Africa, the Middle East, and more into Asia recieved their independence in the 20th century and they were now left to start an entire system themselves. They were ruled under colonial rule for so many years, adjusted to a system, granted independence (well deserved) and now had to start from scratch. And to add to that, the imperial colonists didn't help with the maintainment/building of an infrastructre, government, education system, etc. A lot of people wonder why much of Africa is so in shambles, yes there is poverty, political instability, but the colonialists squeezed the resources out (diamonds, ivory, etc etc) and left them to create their "independent country." These countries are babies with huge economic and political problems and that is reflected in issues such as the lack of empasis given on education. I think it is just important to look at the historical backgrounds of these issues.
Further, ever wonder why Muslims were so ahead of the game back in the day? They developed algebra and contributed to the foundations of analytical geometry. They were the founders of spherical trigonometry. They translated thousands of significant greek/roman works in philsophy, science, math, literature, medicine etc...Christian scholastics borrowed direct works from original Arabic sources and the Latin translations of the works of Al- Ghazali, Ibn Sina, Ibn Rushd, etc. Islamic art style was also transcient in the west with calligraphy, tiling, and geometric patterns. Muslim farmers introduced Spain to many crops such as sugar cane, rice, oranges, apricots, eggplant, ..etc . Even in term of cleanliness, when the Christian crusaders came over, the Muslims were horrified at their lack of hygiene! Even Christian first-hand crusader accounts elaborate on the cleanliness/hygeine of the Muslims they encountered. It is just very interesting how in a way we are going backwards from the developments that have been made. Sorry if I digressed too much, I just have read a lot on this subject.... 😳
