It’s not so much that the bar should be higher, so much that leaving the bar as low as it is provides a signal that contrasts the range of sky high standards New York also makes possible in other ways.
Yes, the subway sucks, but New York’s tendency is to let the full scope of humanity simply exist out in the open, as is, warts and all. This is the philosophy I take away from it.
Should the world standardize a mandatory minimum quality upon public civic spaces? If we did, wouldn’t that require cracking down on deviations from the prescribed norm? Wouldn’t that drive people out, possibly sending some to a place much worse that a dirty smelly subway tunnel? The answers to these questions aren’t cut and dry.
