What kind of work do you expect someone to get when they have no place to take a shower every day ? What kind of work do you expect them to get when it is illegal to hire many of them because they are missing their documents ? No State ID, no SS# card, no birth certificates, no passports.  Those were thrown out in the trash in the last few sweeps.  You expect employers to hire people that stink and have no legal proof if identity ? 
Plenty of them are "hustling" as you call it. Digging through trash cans doing the recycling that many of your "normal" people are too lazy ! to do. "Ahh junks already, jus toss um in da trash" Many are out there pulling 5cents at a time out of trash cans, smelling just like the trash. You want them to go apply for work at 7-11 ?  you going to go to that 7-11 and buy from that person behind the counter ?
Or do you expect the dumpster divers with no education to go apply for CEO and management positions ?
