They're a bottleneck employer - meaning you have one "good" job for a whole lotta crappy ones, and I never heard of a person who started at the bottom as a picker/packer actually being promoted. If one does, thousands don't. So, yeah, they "create jobs" but it's not a REAL job where a person can advance, stay with the company, and retire. We seriously need to bring those corporate ladder type things back.
For example, I know exactly one person of everyone I've ever known who worked at McD's in their lifetime who got promoted to the corporate offices. One. That's what I mean by bottleneck. In the meantime, sometimes you just gotta do whatever you can to pay the bills, and hope you won't be picking and packing forever, or wrapping burgers, tending bar, etc. You keep playing that game of musical chairs.
