The US has been proven time and time again to only want countries to grow on the US' terms (China is the example of a country that was too big to control or stop).
You can look at Cambodia and Vietnam prior to the Vietnam war, and you can analyze the history of Central America to discover why all these places are basically third world still when they have had thriving economies at one time or another. The problem was they weren't thriving on the ideals of Capitalism, rather some of them adopted a socialist workers structure.
The issue is the structure of success and how it feeds into the powerful states and their corporations and not success itself. Success that is not wrapped by Capitalist values is very dangerous to the US, EU.
The reason everyone turned on Hugo Chavez after being a man named in Time's influential people list is that his socialist policies (especially the distribution of oil wealth away from large corporations) started being successful and other Southern American states were taking notice (combined with trade deals with China). Of course, since then he has been shown to be misguided in a number of things so I fear even mentioning him.
