A problem is something you can do something about. If you can't do something about it, then it's not a problem, it's a predicament. That means it's something that must be coped with, endured.
We can't expect to solve problems if all we do is tear each other down. You can disagree with a certain policy without demonizing the person who espouses it.
It isn't that they can't see the solution. It's that they can't see the problem. They can't see the problem if they are looking in the wrong place. They can't see the problem if they have blinders on - for 'none are so blind as those that will not see'.
We have to find the origin of the problem. The origin of the problem in many African countries is that you've got state bureaucracies which are too bloated.
