People who tend to think like you, who can plan in advance, are willing to get a regular job, don't do drugs etc, rarely end up homeless, even in the US. Most of the visible homeless on the streets of large US cities are deeply dysfunctional people, and lower rents or public housing won't make them more functional. Getting them out of public sight would be improvement for the public, to be sure, but the policies of the US cities ran by liberals tend to be extremely ineffective with respect to getting them out of public sight.
