It seems that UAE is literally nothing but high rises or skyscrapers (basically the same with Bahrain, Kuwait, Saudi Arabia or Qatar) while Oman has none of that (since most of the infrastructure is marble white or using bright colors contrasting the sun), though they’re on an even playing field when speaking about their wealth. Is it because Oman has a different approach on how they spend their money or retain cultural heritage?
When the Burj Khalifa was first constructed there’s a flaw, they didn’t install a proper sewer system. So what happened was that “poop” trucks showed up to collect waste in which is taken to a sewage plant. That only ceased when people demanded for a pipe to be installed connecting the building to the main sewer system.
