North Korea is no longer starving. In fact they are growing at about 2-4% due to economic reforms encouraging small scale capitalism and local markets. That being said its a nightmare of a society. 
Investors are a mixed bag for society in general. Sometimes good, sometimes bad.  What about the big hedge fund speculators ? How do you distinguish ? What's the social value of an investor if the money made is not reinvested into the society that created it? Wealth creation is important but unless it benefits the social context in some serious way as it has in the past its social utility is in question. Its the future that has me worried.
