There are exceptions, but most people are indeed paid like this, at the end of the month (or the end of the week). But this is more an outlook than a hard fact.
Another outlook is, the employee should count herself lucky to be authorized to work for a company. The company provide money to the employee, which means it feeds her. If it didn't the employee would have to find another benevolent corporation, or starve. Now there is still the occasional maverick who tries to start her own business, but mostly, employees rely on companies to eat.
Yet another outlook is, the company don't feed the employee. The customers of the company feed the employee. Which is why the customer is king: piss him off, and you won't see him again. Do that too much, and you your employees will starve. It will be your fault, and maybe the fault of some of your employees. It's certainly not the fault of the customer, who has every right to choose what to consume.
I personally find these three views (the one you awnsered to, an the two I mentioned) a bit extreme. But they're not strawmen either. Some people really do believe that. In my opinion, this is the sign of a deep problem. I don't know what exactly, but something is off with the current customer/employer/employee arrangement.
