It's easy to confuse the negative effects of scale with cultural similarities. I've lived in both cities and you'd have to step outside the US to find two cities less like each other.
Its easy to understand why New York magazine would publish high-brow link-bait: the decreasing relevance of banking-- NY's primary economic engine.
The funny thing is that the importance of banking is cyclical. Banker misbehave, markets punish them, they pretend to cower, they quietly recover... and then they misbehave again.
These kinds of comparisons will diminish once it's misbehaving time again.
