If you are familiar with the premise of John Howard Griffin's "Black Like Me", this is like "Poor Like Me". Author Ehrenreich puts herself on an ascetic budget, moves into a rental studio, and applies to work at the far low end of the payscale, documenting her journey as a WalMart employee and a hire housecleaner. Her observations are very astute, such as her dissection of how WalMart makes potential employees feel like they aren't particularly needed, or even wanted by the giant corporation, even as it struggles with manpower issues. It's part of the corporate psychological operations against their (potential) employees, constantly undermining their self-esteem and self-worth so they will accept lower wages. An amazing read.
