Considering the title, the intelligent reader has to understand the reason why the poet used the adjective "ignoble". Looking at the layout we can see that all stanzas are different from each other in terms of length, creating a unique reading effect. Indeed the first two stanzas are fast, especially the second one, while the last one is slow.

After the first introductory stanza, when the crowd is compared to an ignoble procession, follows a second one which is characterized by longer lines. This one in particular is intended to highlight the hectic rhythm of the employees, who are committed into not being late for work. In the same stanza the poet admits his humiliation when watching the ignoble haste of those people, who mingling with each other loose their own identity.

Using the term "wallet-carrying" the poet accuses the economic aspect of being the reason to all this hurry.

People are not human beings anymore, but just running legs that don't know where they're going. All they're scared of is being late.

The second stanza ends with the pronoun I, which means the poet distances himself from the crowd. To complete his work the poet makes sure that the third stanza strucks the reader with its shortness, it's the most important stanza of all and it's where the word humiliating is stressed so that it stays in the reader's mind.

Since humiliating is a progressive aspect it indicates that that feeling doesn't go away, so the message that the poem seems to send is that humans are pressed by economic needs that make them lose their sense of self.
