They don't have full time. Many of the worst jobs in our society are given on part time/hours basis only. And most landlords now a days do background checks. If you have been in prison, had a foreclosure, bankruptcy, etc many places won't rent to you at all. So you have to go to predatory places which charge way more than your regular housing. However, this is all very basic information on this topic. Since you seem to not know these very basic facts, may I suggest not holding an opinion or judgement until you may do a little reading on the topic. It's my experience in my life that when I gave an opinion on something I was ignorant on, I generally felt ashamed afterwards. It's been a big motivator in me trying to know a little before giving an opinion. I think it's made me a better person.
