Used to talk to a homeless guy every week. He had no interest in holding down a job. Begged for money so he could buy beer and nachos. Him and his friends lived in a dog park until they got kicked out. They would all save up money to get a hotel room once a month. Had two jobs given to him, walked out on both. White boy from Boston. Racist, biggest Tom Brady fan. Just didn't want to take part in regular worker bee life.
I Have worked alongside many pillheads and addicts. None of them were homeless.
Two guys I work with now used to be homeless. They worked their asses off and struggle to make ends meet but they aren't going back. They actively look for new ways to make more money.
I see multiple homeless people standing on the side of the freeways entrance with new backpacks, and a sign with too many damn words to read begging for money. Homeless encampment near me a lot of them have bikes and cell phones, only a few are raving lunatics.
First 48, the cops talk to homeless people all the time and they're fully functional people.
Restaurants, fast food places, landscapers, warehouses, etc. All hire illegals. They would hire a homeless person.
There are multiple opportunities for these people to at least work a shytty job but they don't. A lot of them choose to be homeless.
