ELI5: Why do employers look down on homeless people?

I've had a very near brush with being homeless and am currently in a shelter, and I was curious as to why I seem to get less interviews when I state no fixed address on my CV. This confuses me because surely somebody being homeless is more desperate for work, and will therefore work harder.

Human beings are unfortunately susceptible to a cognitive bias called the "just world fallacy". 

The just world fallacy is the idea that, on average, good things happen to good people, and bad things to bad people. The idea of random fate scares us. We would much rather think that the people who are poor and peniless on the street somehow deserved it rather than contemplate the horror implied by the fact that they are there by no fault of their own. 

The same goes in the other direction. We are more likely to hail and respect the people who have happiness and wealth and power, because it makes us happy to think that they got that happiness and wealth and power because they somehow deserved to get it. 

Most people know that this is not the case, but our brains are wired to think this way, so it is very hard not to express this bias in the way that we interact with people.
