True, that may have been too broad of a statement. I probably should have said that was more my opinion or the opinion of those I have heard talk about it. (Like Bill Nye in the above video.)
China’s government today is made up almost exclusively of those with science and engineering degrees, but the political system is hardly a true technocracy even if Nye calls it that in the above video, so it is not a really good representative case for technocracy.
A better example might be Italy, which in recent years saw the Government of Mario Monti. Mario Monti was brought in to solve Italy’s debt crisis in 2011 with a technocrat government. He appointed professionals who he knew had the skills and experience to help him solve Italy’s financial problems; and who were independents without strong ties to any of Italy’s existing political parties. He was somewhat successful in bringing stability to Italy’s finances, his unelected technocrat government were able to make moves that were necessary for the country, but would have been career suicide for any career politician. Unfortunately he was forced to step down before the end of his intended term basically due to the political ambitions of others. Criticisms towards him typically revolve around the fact that he didn’t do enough with the power that he had, or that he bowed too easily to the strengths and interests of the other politically ambitious parties. Most agree that he set Italy on the right path, but are concerned that by bowing out too early, his reforms may not have the longevity needed to be effective.
Mario Monti wasn’t Italy’s first technocrat government, in 1995, the Government of Lamberto Dini was also a technocratic one, with experts from outside parliament appointed based on their skills and experience.
The problems that Monti ran into I think highlight some of the challenges that any technocracy might run into in trying to run a modern government.
