The belief that disabled people are incapable of surviving in real-life situations is belittling and harmful. Many persons who are mentally disabled can meet the challenges of surviving in society. Treating adults like children only prepares them for a lifetime of dependence and being institutionalized.
The belief that people are homeless because they brought their predicament on themselves, is one way to justify doing nothing to help. This rationalization allows society to consider the homeless person as a nuisance, one from whom we all need to be protected by law enforcement.
Our society is in a state of constant surveillance. While this may help solve crimes, it interferes with the privacy of individuals. Businesses are hiring private security forces to monitor the public, especially the poor. It can be crazy-making not to know when and if one is being watched.
