You have no idea what you're talking about.
The towers going up in NYC are strictly based on market demand. It has nothing to do with "show"; in fact these buildings are very difficult to build, due to tough zoning, NIMBY opposition, absurd union rules and the nation's highest mansion and transfer taxes.
As for "efficient" the most efficient residence is the one most reflective of market demand. Obviously these buildings are being built as efficient as possible, because the developer is strictly motivated by profit. The relative success of the building determines the building's value, and benefit to the city.

Gee, you came up with that all by yourself? Who knew that tall buildings had elevators, and elevator capacity was related to building height?
You forgot the little part about not all real estate being created equal. If a ground floor residece is X, A 90th floor residence overlooking Central Park will be sold for 5X or 10X. So obviously the math works out, unless the usable floorspace becomes absurdly tiny. If the math didn't work out, then developers wouldn't be building tall skinny towers, which are much more expensive to build than "regular" highrises.
