History shows that, at earlier stages of economic development, corruption is difficult to control. The fact that today no country that is very poor is very clean suggests that a country has to rise above absolute poverty before it can significantly reduce venality in the system. When people are poor, it is easy to buy their dignity-starving people find it difficult not to sell their votes for a bag of flour, while under-paid civil servants will often fail to resist the temptation to take a bribe. But it is not just a matter of personal dignity. There are also more structural causes.
