Sorry WT how do you think you are using doha expressway, and salwa road, and D, E and F rung roads, and Hamad International Airport, and Education City, and the new Doha Port, and all the new clinics, and the fact that you have water in your taps all the time even though the population doubled in less than 10 years.?
All these things were paid for by the money made in the last 10 years. And with respect to the "vanity objects " lots of them are investments that the country and can now use to borrow money at very competitive rates.
Was there waste? Yes but not as much as you are belivinng, also there was lots and lots of very smart investments in infrastructure and future assets
