Would you describe vandalism as a &quot;market failure&quot;? How about shoplifting? If not, why are they a different problem from littering?<p>If there is a problem with plastic bag litter, it is the fault of the litterers, which is a subset of all users of plastic bags. Shifting what should be the liability of the polluters onto the entire population of plastic bag users doesn&#x27;t right any wrong--in my view the wrong is even greater.
