I totally understand what you say and feel. The problem is bad street photography. Taking pictures of people walking up and down a street with cars as a background going through their heads is totally pointless.
There is Art to be made, but it takes a solid vision. Good street photography is jaw dropping. It's far more complex then just shooting people walking.
Street photography is like Chess. The poor players play utter pointless move that are incredibly stupid. I repeat: Incredibly stupid. But, within their level, those moves are quite acceptable. The masters, though, devastate with every move, even the most harmless ones. And yet, it's the same game.
