Surprisingly no, and even more surprisingly, maybe not anymore than some regular American city.
I mean, people down and out at the least have lots of job options. As mentioned in a comment, they need people to clean hotels, wash dishes, cook etc. the same as in other areas of country, and probably way more so!
The standard exists in Vegas as elsewhere. There’s a fairly normal police force, hospitals, schools – you name it.
The Dark Side?
Well, if you fall – because of casinos or whores – you’re not getting any sympathy! It’s just tough shit. I mean, imagine being in a place like a strip club in Knoxville, TN – except in a place with 1000’s of such places, plus casinos. It’s a world where you have to man up and take responsibility because you asked for it by going there!
Normal America Has No soul?
Life anywhere in the US is tough if you don’t have any credit. I mean, whether it’s Vegas or Small Town Iowa, if you have no credit, banks can’t bail you out. Also, if you’re being a moron with the money – and that could happen with drug addiction or, if in Vegas, casino or strip club spending – then, as noted, expect no help, as maybe even bank loans, assuming you can get one, won’t save your ass!
