Yes, Russia's oligarchy should be curbed by the state, because the Russians do not have representative government. Russia was very strong in the years following the break up of the USSR. Their democracy was developing and people were happier. Things have fallen apart since then, and the oligarchs need to return power to the people.
I am not familiar with anything in Russia but by looking at the things here in the USA I feel that most all regulations should be restricted to the state level, there is no need for federal government to run our lives, I feel the leaders of the state are perfectly capable.
