What does that mean?
If you want to cut to the chase,
Dagny gets a phone call from Minnesota. The rail cars set to haul that state’s wheat have not shown up, and the massive harvest will rot in its silos. People there are beginning to feel genuine terror. The caller says that once he hangs up, he is going to become a deserter. Dagny’s investigation within the railroad shows that every necessary form has been filled out, but the grain cars are not going to Minnesota. She finds that the paperwork has been falsified, and Cuffy Meigs is sending the cars to Louisiana to carry Emma Chalmers’ soybeans, now deemed more important to the government bureaucracy than wheat.
Emma Chalmers, Kip Chalmers' mother.
I think you will find that it is an “Atlas Shrugged” reference...
