Is This a Question of Ethics?

Today is garbage day. Our garbage can is overflowing! Our neighbor's garbage can is only 1/2 full. One of us thinks it is OK to put one of our extra bags into the neighbor's can because it is 1/2 full and adding to his can won't cost him any $$. The other one of us is not buying this rationalization and isn't comfortable adding the bag. One of us marches right over to the neighbor's, bag in hand and places it in the neighbor's can while the other one watches. And speaking of garbage, I heard on the news yesterday night that the average salary for a garbage man in Western Washington is just under $110,000. What the heck?! And all the jobs are union so you know they have crazy good bennies, too! $110,00-go figure.
