I don't know which is worse, me "whining" about the city's disregard for homeless people or you whining about homeless people in your back yard.
Are the camps you mention permanent camps with common gathering areas, central kitchens and fire pits? The Whoville camp had those features, plus a group who were working together to take care of those who were less able to care for themselves, such as Carrie Miller. By all accounts, she was doing much better and becoming healthier in the secure space provided by Whoville.
The camps you mention are probably not as secure since the people camping there still live under the threat of being arrested or cited for being there.
