TEXT A1 MOSCOW, Russia (Reuters)-The personal fortunes of Russia’s 100 richest businessmen are as big as a quarter of the nation’s entire economy, business journal Forbes says.2 "Capital in Russia is not only concentrated in the hands of a small group of people, but also associated with just one city," Forbes said in a press release ahead of publishing a list of Russia’s 100 wealthiest.3 "No other city in the world can boast such a large number of billionaires as Moscow."4 Russia’s biggest billionaire Mikhail Khodorkovsky, the main shareholder in oil company YUKOS, will find it hard to enjoy his fiches, although he too is in the Russian capital.5 Khodorkovsky is worth $15.2 billion, but is languishing in a Moscow jail awaiting trial for fraud and tax evasion.6 The charges against Khodorkovsky are widely seen as part of a Kremlin campaign to destroy the politically ambitious magnate’s influence.7 His arrest has found wide support in Russia, the world’s second largest oil exporter, where the vast majority of people have gained little from the privatisations of the early 1990s.8 "By contrast, the combined net worth of all American billionaires is equivalent to just six percent of the gross domestic product of USA," said Forbes.9 In this year’s Forbes full list of the world’s billionaires published in February, Khodorkovsky was followed among Russians by Roman Abramovich, the owner of English premier league football club Chelsea. Abramovich’s wealth was valued at $10.6 billion.10 On the Forbes list published on February, the other names making up the Russian top 10 were Mikhail Fridman on $5.6 billion, Vladimir Potanin on $4.9 billion, Mikhail Prokhorov on $4.8 billion, Vladimir Lisin on $3/8 billion, Alexei Mordashov on $3.5 billion, Oleg Deripaska and Viktor Vekselberg, both on $3.3 billion, and Vagit Alekperov on $2.7 billion. Which of the following can NOT be inferred from the news
