I think what the author is getting at is that at many office jobs that lower-class folks work at, on your last day you'll be "walked out" by security to make sure you don't steal anything, "cause a scene," etc. The implication is that this is something that happens to lower-class workers, but not upper-class workers. And the "lower-class" job comes with low pay, and thus: poor. That's the logical connection I get when reading it. As someone who used to work in a "lower-class" (and low-pay) tech job (outsourced tech support, but the outsourcing firm was in America) - this is how they treated employees when they resigned (and when they were fired). It resonated with me, and I do not think it's a particularly rare thing in "lower-class" white-collar work.
