3 levels to go
Now I understand why developing and third world countries have such low contributions to the sciences and other creative stuff which contributes to global human potential. Because only a small percentage of people have the resources to reach the 4th and 5th levels. Most of the population is on par with animals, sometimes even lower. It's sad, isn't it, that ironically the lack of resources gives rise to people who have a 'me-me-me' mentality. Even when they get the resources they aren't willing to put their knowledge into practice for the greater good. Yes, I am referring to the bureaucrats.
