I looked up Josh Brolin's career because I wasn't really too familiar with him before Avengers. Damn he's had a busy career. The kind of movie he's in isn't typically what I watch though.
If you're homeless in, let's say, NY for example...a bus ticket to Florida would be 80-100 (just from a quick google)
I imagine homeless people are just concerned with having the funds day to day to buy food
Not to mention a majority of homeless people are mentally ill or are substance...
