Let's be honest, there are not that many examples to choose from. What I like about China is, it illustrates how effective a mostly benevolent dictatorship is. It is the optimal political system imho, provided it remains benevolent of course, which is no small feat. Provided they don't trip and fall, if China is not the absolute supreme leader of the planet in 25 - 50 years I will be shocked.
I just got back from China and the rate of infrastructure expansion is amazing. I have a theory that since they are highly centrally planned they don't really have to worry about if infrastructure is "profitable" in the Western sense of the term. They want to build roads and high speed trains? Well the government entirely controls the banks and construction companies so they just make some money and give it to the co…
Note that building infrastructure "too far" in advance is wasted effort. You end up with infrastructure designed for yesterdays needs that needs updating when you need it. (ie houses with coax that cannot handle digital TV, not wired to internet.) You also lose any useful advances that might happen (brand new never used air conditioners that use so much energy you can buy a new one just on the energy savings over a couple years)
Use you need to plan and build for tomorrow. However do not do too much as you don't know what tomorrow will bring.
