These hierarchies are omnipresent. The mere feat of creating platform higher than sea level or the level that could be considered "ground level" stems from the conquering of gravity. Nature's very own gravitational pull that exists wherever we go gives value to the creation of raised platforms. It is not surprising that we, as a civilized race which can use the tools at our disposal and build upwards, have challenged Mother Nature and pushed the boundaries of the possibilities of height since we could lay a brick on top of another. Why are the Pyramids at Giza so awesome? We marvel at the feat of the Egyptians (also believing that it is beyond human capabilities) for their defeat of gravity. Not only does height play into equation, but the mass or each massive brick adds to the unbelievable accomplishments of the Egyptians.
In the not so distant past, the production of steel and the boom of industry allowed us to build upward without building outward. The skyscraper. Its very existence stemmed from the lack of space as a result of rapid urbanization with the birth of the high-rise. Citizens need places to stay in the city. What corporations did with this creation continued the Antigravity Race among others and Mother Nature again.
The extremely capitalist world of America during the beginning of the 20th century and the new possibilities in construction became the new Olympic grounds for large companies to compete. Whoever could build a larger building and could fight gravity the longest and hardest was obviously the better company. It was a show of their money and thus the hierarchy was made apparent and clear. Pretty soon we began building beyond our physical capabilities. The stairs that had once gauged the size of the building became almost obsolete, now only required for safety reasons. The invention of the elevator was the fix for the busybody citizens of New York and Chicago. Nobody had any more time to use the stairs. It was too much of an inconvenience anyway.
