In 1935, the Federal government build its first public housing project in Atlanta, GA. After 86 years of 'affordable (i.e. "FREE") housing', homelessness is bigger than ever.
'Affordable housing' is not the answer. The solution to reducing homelessness is to stop subsidizing homelessness. Cut off free wifi for the homeless of Seattle and Portland, and you will see them taking their $1,500 laptops elsewhere.
