One should carefully consider whether removing a current problem might lead to an even greater one.
Aristotle informs us that Æsop told the following fable to the Samians during a debate about changing their ministers, who were accused of plundering the commonwealth:
A fox, while swimming across a river, got entangled in some weeds near the shore and couldn’t free himself. As he lay there, swarms of flies gathered around him, biting and sucking his blood. A hedgehog, noticing the fox’s plight, kindly offered to drive the flies away. “No, thank you,” said the fox. “If you chase these flies away, who are already full, a new, hungrier swarm will come and rob me of every last drop of blood.”
