I've had this theory for years now. It came to me originally when I escaped retail work and got my first office job.
You can tell how much a job values you based on the toilet paper they provide you.
When I worked retail, first at Subway as a “sandwich artist”, then Target as an “electronic specialist”, then later as a manager at GameStop there were two things I noticed. First, all three companies treated me with contempt and were more concerned that I might be stealing from them than if I had the resources to do my job properly. Secondly, the toilet paper sucked.
Later, when I got a cushy data entry job at Chase bank I noticed two similar things: my bosses were far nicer to me and the toilet paper was a little nicer.
The more jobs I've had the more I've noticed a relationship between how well I'm treated and the quality of TP provided.
GameStop treated me like the scum of the earth and provided a sandpaper esque single ply for their bathrooms. This stuff was bible paper thin to boot.
My current job treats me very well, offers profit sharing, and stocks the bathrooms with Charming.
Tldr; the worse a company trears your ass the less they think of your ass.
