Plutocrats have a certain grudging respect for one another. Naturally, they would like to put each other out of business unless it impacted their own business adversely. So I conclude that Obama's sanctions are an attempt to isolate Putin from his plutocratic supporters (although perhaps supporters is too strong a word; Putin keeps his plutocrats on a pretty tight leash, just ask Mikhail Khodorkovsky).
But what if under the table the West is inviting Putin's plutocrats to join them, where the grass is greener and you don't have old Vlad busting your chops. We're not going to mention that we're going to give you a haircut on the way, but are you really ready for the rebirth of the Soviet Union? The London bankers must certainly be for it.
On the other hand, you have the Chinese promising big business... but China's biggest real estate investor is unloading everything as China replicates the Western real estate bubble and collapse....
It's tough being a Russian plutocrat these days. It's tough being a plutocrat anywhere, really, with all this talk that plutocrats are *too* wealthy (and are actually mass murdering their fellow humans with their insatiable greed by hording wealth and depriving others of health care, education and jobs).
Come to America! Come to the UK! Plutocrats rule! This is the subtext of what the Russian plutocrats are hearing.
