They used to tell me I was building a dream, and so I followed the mob,

When there was earth to plow, or guns to bear, I was always there right on the job.
They used to tell me I was building a dream, with peace and glory ahead,
Why should I be standing in line, just waiting for bread?
Once I built a railroad, I made it run, made it race against time.
Once I built a railroad; now it's done. Brother, can you spare a dime?
Once I built a tower, up to the sun, brick, and rivet, and lime;
Once I built a tower, now it's done. Brother, can you spare a dime?
—“Brother Can You Spare a Dime?” by Yip Harburg
