Russian President Vladimir Putin said Tuesday government and businesses share responsibility for rampant corruption in the country. Commenting on a letter to Putin, published Tuesday in the newspaper Moskovsky Komsomolets from rock singer Andrei Makarevich, saying \"If no dramatic changes take place, this situation may lead to a total catastrophe,\" Putin suggested a similar letter should be addressed to Russian businessmen. \"The fact that the state should step up its anti-corruption efforts is evident. A second letter should be addressed to entrepreneurs, because to a similar degree, they provoke such situations,\" Putin said, adding that businessmen \"choose this path when trying to get a competitive advantage over their rivals.\" In his letter Makarevich said and average kickback in Russia has reached 70 percent, sometimes as high as 95 percent, or a business deal, and that courts \"are either an instrument for punishing undesirables or a mechanism for taking money from plaintiffs.\" Corruption has been a pressing problem in Russia for years. The country ranks 143rd or 182 countries in Transparency International\'s 2011 Corruption Perception Index, the Russian news agency RIA-Novosti noted Tuesday.
