Problems don't exist independently from those who define them. Thus, a sense of unease is defined as a problem only by those who believe that a problem exists. Many of today's problems are so complex and so far-reaching that their complete dissolution is unrealistic. A more realistic expectation is to improve a complex problem situation. Correspondingly, no magic solutions exist, only ideas generated by humans to solve their self-defined problems.
People have different views of the same situation.
A problematic situation is viewed differently by the people affected. What may be an engineering problem for a dam builder is viewed as a cultural problem by the native inhabitants of the land to be flooded. Each group impacted by the situation defines the problem in its own terms, with each problem definition simply being a different aspect of the same phenomenon. Thus, there are no reductionistic problems, only holistic problem situations. People disagree on what's the actual state and desired state.
