I don't think we're terribly far apart on any of this, Martin. As you know, I have no problem disagreeing, and I can do it without heat too.
The problem you're pointing to is the fact that there's good street and there's bad street, just as there's good landscape and bad landscape and good portraiture and bad portraiture. Yes, I see the hipsters hanging out in gentrified neighborhoods and meaningless pictures of people crossing the street at traffic lights too, even in books that pretend to define the genre. The pictures of homeless people just tick me off. It's so, so easy to shoot meaningless pictures of pathetic hoboes, and people who do that are after the easy way out. And I don't think what you're saying is harsh. To me, the classic repository of this kind of garbage is Jackie Higgins's 2014 book,
The World Atlas of Street Photography. There are others, but that one tops the pile.
But what about
THIS? This is one of my favorites from Garry Winogrand. It's nothing like a hobo picture or hipsters hanging out or who-cares pictures of people crossing at a light. This is real street photography, the kind of thing that defines the genre. It's powerful, unfortunately powerful in a sad way. But real street can be powerful in a happy way, in a reflective way, or in a funny way. For funny check Helen Levitt. If you've seen enough of Winogrand's street work or Robert Frank's street work or Levitt's street work you'll know real street when you see it too. In case you didn't check the reference I gave you, I've attached one of my own. This is not a hipster or someone crossing the street. It's not part of the urban scene. It's something that stirs reflection in me just as Winogrand's picture stirs reflection in me. That's what real street is for.
