I don't know that anyone is really contented in this story.  I don't think even the con man is content.

To me, the real contrast in this story is between people who are basically honest and those who are not.  The story seems to imply that the world works to the benefit of those who are not honest.

I say this because the con man really comes out ahead in this story while Gortsby and the man who lost his soap lose.  Both of the latter two men were not doing anything wrong, but they lost out.  The con man ends up with their possessions and they end up with nothing.

So I think it's a statement about how the wicked and aggressive rule the world.
