Corruption is rampant across America, the UK and Ireland - countries where "wealth" expanded massively among a tiny minority over the last 30years. Last time I looked it was the corruption of the American and UK financial markets which has brought the world economy to its knees and consigned the Western nations to a terminal decline.
You can point the finger at China and Russia all you like - but that doesn't diminish the rampant corruption in you own back garden under your own system.
The evidence of the last 5 years shows that the business community, markets and governments were in a virtuous circle of turning a blind eye to rampant market corruption - and it all happened because it was opaque to society because of a light regulatory touch and a regulator who was asleep on the job, and it is still going on at a massive scale.
I live near a housing estate which is full of people with criminal records, drug and alcohol addictions, no qualifications and anti-social tendancies. These things are responsible for their deprived situations not a corrupt financial situation. From my life experiences your perceptions of some kind of conspiracy to keep people poor is just wrong.
