The implication is that the majority of homeless are just lazy, yea? Just pick apples!
I've been exactly there. You're not making minimum wage when you show up to the farm to pick apricots all day.
Bars - need a bartender license. Yes, you do, nobody is risking it in 2018.
Restaurants, sure, but again, you're not making minimum wage, and if you whiff of hobo you're not working front of house and getting tips.
Cleaning jobs are usually cornered by some immigrant class . If you're an immigrant and have friends/family with the hookup or maybe can speak their language, congrats, you're in (not making minimum wage). If not, move on.
Roofing - you need to bring your own tools. Speaking from experience. Also, this isn't just a "show up and do it job," the shysters that manage to sell shit crews to homeowners never last long, so you'll have to get on with a crew that know what they're doing, and they're not going to want to bring someone on that wants to just do it long enough to "get their feet under them" and then bail. Decent pay, sure, but it's a "career."
Painting - this means standing outside of home depot, just like OP said. Not minimum wage.
Other forms of low skill construction - like what? It's not "low skill," the immigrants you see doing it get trained up by their cousins on the job, and once again, it's bring your own tools.
Landscaping/yard work - market cornered by immigrants and highschoolers. Nobody wants a random hobo mowing their lawn. Maybe you can get on with an immigrant crew. Non-minimum wage.
>unemployment rate so low
Yea, because people are being paid like it's still 1991 (the 2009 raise was putting a finger into a ten meter diameter hole in a dam).
This guy didn't have a family to support him. That's how the immigrants do it, in case anybody is wondering - they stay with families, get jobs due to families, and afford life here because they're all supporting eachother. Random hobo programmer dude is going to have a MUCH harder time scrabbling out of the hole.
Yea, you can scrabble a life, but you're not building a ladder out of the hole for yourself. I'd argue, if you can program, the 3.75/hr you'd make for 3 months is meaningless if you can instead spend that 3 months homeless but then pull a programming job for even a month.
