“我曾经修过一条铁路,使它运行,让它与时间赛跑;我曾经修过一条铁路,如今它已建成——兄弟,能给我一角钱吗?这是二十世纪美国经济危机期间相当流行的一首歌。那一个个普通工人,在烈日下挥汗如雨,可却依然饥肠辘辘、流浪街头。兄弟,请给他一角钱,好吗? ”I used to repair a railroad to run it and run it against time. I used to repair a railroad. Now it's built. Brother, can you give me a dime? This was the equivalent of the U.S. economic crisis of the twentieth century Popular song, an ordinary worker, sweating in the hot sun, but still hungry, wandering the streets, brother, please give him a dime, okay?
