IMO, street photography is a low art form. It's walking around without a plan, snapping random snapshots of people and expect some meaning to come out on its own. The creation process is regulated to pressing a button and some minor processing. Perhaps similar to throwing buckets of paint at a canvas and seeing what comes out.

It's usually derivative. Someone alone looking sad because that's their resting face. A black and white high contrast photo of an old person. A homeless person. Political street art (that someone else created).

Some exceptions of course, like Humans of NY where arguably the main part is the backstory and writing behind the people they capture with permission, but that's more portrait photography than street.
