Politicians are very fond of regaling us with their vision of the future.
Gandiose plans for social and environmental engineering are placed before us, in the expectation that we will "buy into the dream".
There is one significant shortcoming to these plans, and the politicians' vison of "utopia".
The plans have 5-10 year time horizons, yet the average shelf life of a politician is 2 years or less.
In other words the plans will never come to fruition, because the person who originated them will have gone elsewhere and will be thinking up new plans.
