Kenya is not chile. Pinochet did not steal as much as Kenyans. He was extensively investigated from crimes against humanity, corruption, etc and was found to only have about $5 million dollars (nothing for a dictator like him who'd been in power for almost 30 years)
Also, Chile, unlike Kenya has Germans. Germans are known for their high productivity rates. Kenya is a different ball game. It's a country of semi-literate, village bumpkins and farmers. What do they make?
Let's start with the fundamentals, what every nation must have to establish a stable, sustainable, widely shared prosperity. These are not just ethical niceties--these are the foundation of economic security.
Consider corruption. Corruption isn't just a "values" issue: corrupt societies have corrupt economies, and these economies are severely limited by that corruption. A deeply, pervasively corrupt economy cannot get from here to there.
Corruption acts as a "tax" on the economy, siphoning money from the productive to the parasitic unproductive Elites skimming the bribes, payoffs, protection money, unofficial "fees," etc. By definition, the money skimmed by corruption reduces the disposable income of households and enterprises, reducing their consumption and investment.
"Income" derived from corruption is the classic example of "unearned" feudal rights being imposed on serfs, a broad-based "tax" that keeps them impoverished.
The other side of the corruption coin is transparency: thus it is no surprise that Transparency International is the organization that monitors corruption globally and that issues its annual The Corruption Perceptions Index that ranks countries/territories based on how corrupt their public sector is perceived to be.
The top of the least--most transparent, least corrupt--are Denmark, New Zealand, Singapore, Finland and Sweden, with Canada, Netherlands, Australia, Switzerland and Norway close behind.
There is no way for a deeply corrupt society to get from here (their current level of development) to there (a higher level of development) because corruption limits two essential components of sustainable growth and widespread prosperity: social mobility and innovation.
In corrupt societies, potentially profitable innovations are quickly stolen, copied, pirated or appropriated by corrupt officials and/or criminal cartels. The innovator cannot reap the fruits of his innovation. His only choice is to move to a nation that offers him the freedom to develop his ideas and drive and keep the yield for himself and his family.
