.... but I see the world in 50 years as a much better place. Unless something extraordinary happens.
Well if you live in Russia your statement above might turn out to be true.
Current predictions are that in 50 years the bread basket world, America, will have a harvest session pattern very similar to what Russia currently experiences and Russia will equal or exceed the number of harvest days North America currently enjoys.
The economic indicators you cite will melt away and replaced with something very different in 50 years.
For example, in the US, Florida will sink by 50%? The Outer Banks in NC will disappear. Coastal flooding will make a significant portion the population to re-locate.
On the bright side we will finally have a North West Passage. Commercial test runs have already been conducted. Hey!!!!

The Russians are pleased.
