Can "I, Too" by Langston Hughes be said to connect to the American Dream or simply just American life?

I actually think that both views are valid in regard to
this poem. If we have a careful look at the poem, we can see that there is definitely a
dream of equality and success in the second stanza, when the speaker, having described
how he is separated from others in the first stanza, dreams about a "tomorrow" when he
will not be excluded and shut away:

Tomorrow,
I'll be at the
table
When company comes.
Nobody'll dare
Say to
me,
"Eat in the
kitchen,"
Then.

This
offers a hopeful dream of the equality and success that can be related to the American
dream. However, principally, I think this poem relates to American life and the racism
that it featured and authors such as Hughes challenged and raged against. Note the way
the poem ends with a clear declaration of how the speaker should have the same rights to
sit at the same table as
whites:

I, too, am
America.

He is demanding that
his own status as being part of America is recognised and acknowledged, not just
conveniently ignored as he has been shut away from the others in the kitchen. Thus the
poem sees to say more about American society at the time of writing, although we can
clearly link it in to the American Dream.
