WM and MD jobs are not there for you to "actually live" on them, most of them are not. WM has over 2,000,000 employees, those are starter jobs, as in: you have no skills, you are at the beginning of your professional career, or maybe you are a new immigrant and need the first job in the country, type of jobs.
They're not really what you believe they are. You clearly have never worked in such a place before. The minimum wage plus erratic hours is designed to ensure that you're stuck working there, it's difficult to find the time to seek out new jobs if you're also a student, parent or both. The mere fact that there are people at Walmart who have worked there for over 20 years in a low-end, low-wage position proves your point utterly false.

I haven't yet heard of an app for smartphones that can monitor its surroundings (via mic, camera, etc) without making the phone user aware that it's running.
I'm fairly sure this is referring to the Glass app that acts like a face scanner, a more casual term for a device capable of utilizing facial recognition technology in order to identify someone by their face alone. Surely it's a play on the fact that the original quote is, "Through a glass, darkly," where glass (ostensibly referring to Google Glass) is replaced with the term for its new capabilities.
In reality, it would work better to take the preferences, then do the opposite.
Right, because that's how you foster positive employee morale.
