That line is definitely true. After getting into a decent and safe living world, I ran into a situation. I was given advice on how to deal with it, and I swore I was talking to aliens. It really gave me pause and showed me the brutal reality of how different our worlds are. When I told others about the advice, they looked at me and said "wasn't that obvious to you?" Well, no it wasn't.
In my experience, getting out of poor is a multi-pronged deal. Getting out is 1/10th of the battle; the hardest part is not falling back in. It's like being dropped into the ocean with a canoe, while everyone around you is in steamboats.
