What are some similes in Brother can you spare a dime the book?

* "They used to tell me I was building a dream,

And so I faced the phantom blocks of stone,

But now the dream has all come undone."

* "Once I built a railroad, made it run,

Made it race against time."

* "Once in khaki suits,

Gee, we looked swell,

Full of that Yankee Doodle-de-dum."

* "Then I was just as you are now,

And I know what you're thinking, brother,

You ain't got a chance to survive.

Make the best of what's left, and don't ask why,

Why should we live in this hungry land?"

* "Got a coat that's getting thin,

Got a hunger in my skin."
