Rafic Hariri: legacy of corruption

So this issue of the Economist has a very tough piece against the Kirshners in Argentina. It gives this as evidence of corruption: "This showed an increase in the first family’s wealth from $2.3m in 2003 to over $12m." But Rafiq Hariri started in government with less than $4 billion in private wealth, and died with more than $16 billion to his name, according to Forbes, and yet we did not see anyone in the West complaining.
