Additionally, this will require the support of the local government, but many governments will not support these. Because in most countries, funds could be better utilised. In developing countries like India, if the government invests all its funds in such projects to build the tallest building possible, it will be a huge wastage. This is why even in China, recently, the Chinese government passed a law that that they will not allow any building to be built taller than 500m. Any building being built taller than that would be simply for vanity.
Practically, it is a wastage of money The energy consumption of such a building would be very high and public funds will be wasted. And since there was no need, they banned it. According to the laws of the Chinese government, in cities with up to 3 million people, the height limit for the skyscrapers has been set at 250m.
It is really important to pay attention to one thing here. there are very few cities all around the world where the socio-economic factors would allow the world’s tallest building being built there. About 100 years ago, these cities were New York and Chicago. That witnessed an economic boom.
