I think it's largely what you want it to be, but in the end you, the photographer, don't have the say.

Photography Annual or perhaps
it was Color Annual - they were both put out by
Popular Photography magazine, which I hardy ever found, and the annuals only came my way because I'd haunt the kiosk in Glasgow's Central Station during that period, wishing and hoping I'd find something American and photography-related that I could afford to buy on my apprentice's pay; yep, just like rock 'n' roll then. I seem to remember the Leiter spread in the
Annual was entitled 'A Painter's View of New York'.
(Incidently, despite Bailey's access, Leiter shot what I think are the most beautiful images of Shrimpton that I have ever seen.)
Some other, later, gallery-favourite 'street shooters' are credited with being the first to do it in colour; not so: Leiter and Helen Levitt were pioneers.
If you read Winogrand's quotation in the second link, you'll see he had his own thoughts on 'street'...
Thing is, if you are really in the life (in whichever photo-genre) and not the pretence, you just do what you know that you have to do. Simple, really: it's taken out of your hands by your own nature.
Whether you can crack a living at it is neither here nor there; Garry had to teach and do other things just to pay the bills; Arbus killed herself, and many others have followed the route to ending the inner struggle that stops you falling asleep at night and ruins much of your life... and that's why so few people today ever achieve the heights that some old-timers did: they generally can't take the pain, and have a second string that keeps them comfortable so they can go out to play at the weekends. Some call them warriors, I think.
But anyway, folks here only chat about the Americans or the French (real or adopted)) street guys; few are even aware of the Italian school of neo-realist photographers. It's really an immense world if you look for the detail...
