The original 1990's oligarchs used criminal methods - including mafiya tactics and intimidation, rigged no-contest auctions of state assets, tricked their workers (who were naive) out of shares etc. Much of the proceeds were sent to New York, London and Tel Aviv. This was during the chaotic Yeltsin years when Russia's economic landscape was known as the Wild East. These oligarchs were brought to heel by Putin - most famously Boris Berezovsky and Mikhail Khodorkovsky. But also others.
Later under Putin there was a much larger group of businessmen who participated in the economy and had access to opportunities - and the general level of prosperity for ordinary Russians rose significantly too. These are undeniable facts and a matter of record.
No I am not saying that corruption was eliminated, there is probably still a relatively high level of corruption in Russia, but it is certainly better than in the 1990's.
Lol, my sweet summer child. Your naivety knows no bounds.
Boris was anti-Putin and when he became a liability he was killed. Same with Mikhail (he is just managed to keep alive though).
They fell on the wrong side of the corruption power plays when Putin came to power. You ignore the oligarchs from the 1990's who were friendly to Putin.
Far more in number than the 2 or 3 that lost to Putin's power grabs.
Abramovich? Got rich in the '90s, by profiting off the sale of ex Soviet assets.
Timchenko? Who Putin gave an oil exporting license in 1991.
Rotenberg? Putin's childhood friend. Traded oil from Finland in the '90s.
Deripaska? Who in the '90s, while still at University profited off sale of ex-Soviet metal infustry and established large aluminium manufacturing companies in partnership with Abramovich.
Usmanov? Also benefited off collapse of '90s Soviet industry and became a minning and construction magnate.
Why have these oligarchs from the '90s, not been brought to heel?
