What's the poem's tone up until the last line? "Richard Cory" by Edward Arlington Robinson

In echoing
the previous thoughts, there is a tone that praises and attaches an almost reverential tone to
the description of .  The language employed demonstrates this.  Notice the "crown" in
line 3 and in lines 4 the description of him being "clean favored, and imperially
slim."  This tone through language continues throughout the poem.  The fact that Cory is
wealthy creates the perception that he, in a way, is better than everyone else.  In this tone,
rich or wealthy translates to superior, not merely different.  The poem's tone creates this
aura, especially in the last stanza where the speaker indicates the struggle in daily existence
for those who are not wealthy.  Of course, the last line changes all of this and helps to
undermine the tone.  While the perception of Richard Cory might have been rooted in a belief of
superiority, this is not necessarily the case as the last line raises issue that the perception
of individuals could be vastly different than their reality.
