SANTIAGO – First, there was one disappointed foreign entrepreneur. In December, Israeli venture capitalist Arnon Kohavi, whose firm had been lured to Chile by a government program to promote startups, announced that he was leaving. A handful of monopolistic families control the country, Kohavi declared to an online magazine. Worse, these families don’t care about anything except their money. They don’t have to: the country’s natural resources are a disadvantage here, because the rich don’t need to work hard.
