You're right, depending on how you itemize things. However, there's $1B+ spent on human welfare and neighborhood development [1], much of which crosses over in one way or another either supporting the homeless or trying to not make people homeless with programs like food banks. If you look at where that's going [2], you'll see the areas with the highest unemployment are getting most of these funds.
