Just having people in your country doesn't equate to economic productivity. Western nations will want highly educated young people doing hard mechanical labor that often takes two decades of training to get proficient at.
And yes, we will reap the most educated and skilled from less developed nations throughout this century. Which.. just condemns said countries to perpetual destitution. If the best and brightest you invested in leave to go to other countries you both have no incentive to invest in them in the first place or you wasted your economic surplus that is needed to progress your society towards becoming industrialized in itself.
The uneducated poor of the world are not useful to industrialized society. Its why every industrializing nation always adopts universal education to at least make capable laborers out of the poor. Its unlikely to change without world powers deciding to be way more altruistic about their economic exploitation of the poorest regions of the planet.
