Apparently to zero, and if we're to believe the article, he's been made to starve under the bridge too (if I'm to believe the countless HN threads about homelessness in the US, this is how being homeless looks like).
Food is relatively accessible in the US for everyone but there are of course difficulties for people who need help knowing about the resources available to them or practical difficulties in taking advantage of those resources (lack of transportation, scheduling difficulties with children or one or more jobs, etc.)
Accommodations underneath bridges and even worse places for our homeless are unfortunately a widespread issue in the US.
