Mikhail Gorbachev has died

The United States didn't do enough to help Russia transition to democracy in the 1990s. There was no "Marshall Plan" after the Cold War like there was after World War II. This was a huge mistake, and we see the consequences now, with Russia having turned back toward totalitarianism and imperialism. Sadly, it seems that Gorbachev's efforts were mostly for naught. But it was courageous at the time to open up the Soviet Union to glasnost and perestroika.

Of course Yeltsin was a big part of the problem too.

I think the big difference is the oligarchs. The USSR had already been transitioned to a resource state, and there was no actual rebuilding that needed to happen. The Marshall plan was almost easy because you could tally up all the broken bridges and say “itll cost us $X to fix”. What’s the equivalent for post USSR? What ended up happening was oligarchs swooped in to take over from the central planners, and it’s not clear how the US could have helped steer it differently short of going to war with Russia’s upper class.

I think you have this upside down.

The oligarchs didn't swoop in and ruin everything. The Russian government did not want their resources and industry controlled by foreign share holders, so they were dead set on privatizing the economy by selling to Russians only.

With this constraint, the handful of Russians who were able to raise capital in such a short time, without foreign counter bids, got the privatized businesses far below market prices as a result. This is what made them billionaires, and turned them into the oligarchs.

Which ever way the cause and effect happened, I think parent's point stands that there was little the US could have done to intervene.
