If you're wondering how the "riches" part applies here, just bear with us, we think it'll make sense. Shukhov feels ill here and has a stressful morning in the camp where he is unjustly punished for "sleeping late" and is turned away from sickbay. He then has to line up and march to the worksite for a long day.
Shukhov's day starts improving some. He and his gang get a decent assignment, he gets some extra food at dinner, and he finds his work as a bricklayer enjoyable.
After a frantic rush to finish his job, Shukhov is nearly late lining up and gets yelled at by hundreds of tired and angry men. Then the gangs are all late leaving the worksite since another worker was missing. Shukhov is frustrated and tired.
Shukhov makes it back to camp at an OK time and his time is his own now. However, he must pick up a package and get through a chaotic scene in the mess hall.
Shukhov ends his day happily after he picks up some good tobacco and earns a reward of food after helping out a fellow inmate. See? He has "riches" now.
