Public Education
I believe educating the public at-large is the first step to anything that we do. In Austin right now we have housing vouchers, but the vast majority of landlords refuse to rent to those with them. The general public believes the homeless "want" or "deserve" to be where they are. Once we dis-spell those myths and make them understand housing is cheaper than them remaining on the streets, we'll get the necessary support.
The city is currently considering banning discrimination against those with public funds for housing. We next have to break down barriers for those with criminal records.
