Yes, with training even a chimp or the dumbest in our society could do most tasks, but that does not make them an intelligent problem solver.
A lot of problem solving comes from experience, not just "intelligence". I know some complete morons who could replace a head gasket but can barely do math. They have been around it their entire lives and just know how to do it.
