Do you realise you're supporting my point of view?
These African countries did not have "long enough to get their acts together!". They haven't been given the chance to get their acts together.
About China and Russia: I agree with you, no arguments. If I didn't mention them explicitly it's because their influence on those African countries is historically much more recent than European/US one.
No, what i realise is that you made an assumption that 'long enough to get their acts together' meant that they should now be on par with the west. My statement was that they either move towards a social program which is beneficial to all. It doesn't matter at what stage of this transposition they are at, as long as the people can see that progression is being made and to their benefit, which it doesn't appear to be. They've had long enough to implement these programs and it ain't happening.
Then you blame the West and the USA for exploiting these countries! How do they exploit them? Well they can't do what they did in the past and colonise the country for it's resources and cheap labour force so now they offer enticements to these governments. So the question is, who is the bad guy in this situation, the enticer or the enticee? My answer is that they are both equaly complicit at the expense of their citizens. 'Luckily' some governments will allow the wealth to trickle down to it's citizens and there are others who hoard it and their citizens get squat. So while it's easy to blame the west, consider also that governments who abuse their power, not just in Africa, also have a moral obligation to their citizens which in most cases 'ain't happening'.
