The advantage of a skyscraper is that land costs money, but air is free.
In other words, if I want a building with 250000 square meters of space, I could buy a 500x500 meter plot of land and build a 1 story building on it, or I could buy a 100x100 meter plot of land for about 1/25 the price and then put a 25 story building on top of it. I'll lose some of the savings in increased construction costs, but probably not all of it, particularly if the building is in the downtown of a major city where land is really expensive.
