That's simply not true. Take a look at Google maps and you'll realize the vast majority of residential high rises are actually filled with equipment, huge fans, loud air-conditioners and empty space. Most have terraces and pools on lower floors, and most penthouses don't have rooftop access.

For example, look at the below image of high rise condos in Chicago. They're all filled with heavy equipment. They're not filled with the super rich having extravagant cocktail parties.
