Agreeing or at least taking into consideration everything said here before me, I would like to give my answer to the question.
First, have you ever been impressed by the skyscraper? I suppose you did, like everybody else. This is because the thing is really impressive, it is huge, it goes to heaven, it has it's sort of beauty, technologically advanced beauty. From outside. But let us take a look inside the skyscraper, the first few stories are usually used to impress on purpose, interiors are extensively decorated in a modern way, luxury shops and ads are installed, most recognized brands are invited to put their world renowned logos everywhere.
Do we have an example of this kind of an impressive building in the past centuries? Does it remaind you something from the past? The history of architecture knows such example. This temple.
Everywhere, in Rome, India, Persia, Tibet, Russia, Greece, France or Germany, the king will build a temple when he wants to strengthen his influence in the area. Especially in the freshly conquered, annexed, colonized or by other means possessed territory, where current architecture is centuries behind what the king could build with his power, money and people.
The temple will dominate the lesser buildings and will convey the populist messages to both, the locals who will think the king is come not to war and rob but unite people under right and mighty God, as well as to king's settlers who will be attracted by the building and all associated infrastructure, culture and economy.
The view on skyscrapers as tall buildings is not complete, the skyscraper is a tall building that was made impressive on purpose. For instance Empire State Building is surrounded by other very high buildings, but you may think they are just tall buildings whereas ESB was definetly build and named to impress.
In colonies such as HK or Singapore the skyscraper will attract both local population and metropolian settlers. Locals will love to move in and learn English to be closer to civilized world that for them emotionally is a "skyscraper world" with technology, knowledge, power and gold. And settlers will love to come as they will feel in the West while being far from home. British colonizers noticed that it is much easier to attract settlers, especially noble and wealthy if you create a very dense town, this will help preserve a metropolitan culture as well as opposed to dissolving in local population.
Of course a decision to build impressive skyscrapers in the colony will not be made by public democratic procedures. Instead it will be made in private clubs in comfortable chairs surrounded by cigar smoke and expensive wine on the tables. Of course both press, the one oriented at metropolian settlers and the one oriented at native settlers (say Chinese in HK) will be told other things about land value, great symbol of our city success, a better place to work and trade for us all. Of course all those messagess will be true as well.
In Russia and China the governments are frustrated by the fact that local popularion sees the West as the more attractive place than the someone's own country, that is why Chinese government will support building impressive buildings. Someone mentioned 7000 skyscrapers build in China. Of course all economical reasons apply, and they have been discussed before me.
Russia did not built a single skyscraper for about twenty years, although the attempts to build impressive structures in Moscow and Saint-Petersburg were made all the time, but each time when the plan was made public, the western press will start the campaign against it, usually the arguments were historical city view, money comes from bad oligarchs, local people will oppose. And they will oppose, few days later when the same arguments will spread in local press. And photos of few protesters will circulate in Western press another few days later, and few other days later they will circulate in local press. I talk about it in such detail to support my claim that skyscrapers are built or not built not from solely natural economical reasons but on purpose. The purpose is populism, who has the right to build temples he is the King. In recent years Russian president Putin used his presidential power to remove the barrier and skyscrapers are finally being built in Moscow.
Not only empire builders and colony establishers would want to build impressive buildings, corporations will want to impress their higher staff, partners and customers. But they have limited power and will only build where allowed by city planners.
