Sorry BAG but I have to disagree with you here. Plenty of third world nations have (or potentially) heaps of money, nations like Indonesia have lots of oil, Thailand has massive exports with food and finished products.<br> <br>

The problem is twofold, 1. Skills Shortage. The education systems in the third world do not produce many skilled labourers like Electricians, Fitters, Boilermakers and Architects and certainly not to the standards of the western world. 2. Politics, corruption at all levels as well as lack of standards and standards enforcement means that buildings that are clearly unfit or will fall down as soon as a strong wind blows are built. Going back to the labour situation, in the west the government forces you to use certified architects and electricians (enforcing standards) but they cost double a basic labourer, in the third world a few units of the local currency into the right hands and you can employ barely trained workers for any complex task or pretty much whatever you want.<br> <br>

Imagine for a moment how rich Sierra Leone would be without all that war, a dictators wealth would rival that of Carlos Slim or the sultan of Brunei, a non dictatorial government would have turned it into the Monaco of Africa.</p></div>

This "more stretchy" steel won't necessarily help with either of these.

<tokenext>Concrete is not " stronger " than steel , it is simply better in compression than steel ( it can support more weight ) .That is wildly incorrect .
Concrete is very usable in compressive members , and is used for a variety of reasons ( cost being an extremely important reason ) , but none of the reasons is because it is stronger than steel .
High strength concrete is defined by the American Concrete Institute as having greater than 6000 psi compressive strength .
Concrete with 12,000 psi strength is used in structures requiring high performance , and represents a slightly higher strength than was thought possible in 1970 .
You can get concrete of 19,000 psi strength if you want to pay for it.Regular dirt cheap time honored 1012 carbon steel had a strength of about 50,000 psi .
Concrete is not stronger than that , eh ?
High strength structural steel is at least 80,000 psi .
" Maraging " steel 's strength is over 200,000 psi and up to 300,000 psi.Strength to weight ratio is of course what matters , and here concrete looks considerably better because of its low density .
In these terms it 's close to so-called high strength structural steel , but does n't even come close to something like maraging steel , and is outperformed by plain old 6061-T6 aluminum alloy .</tokentext>
