The essential MO is the same; the man rises, the family fan out and work the connections; the connections bring new connections and opportunities to them, and so it goes, onwards and upwards. China’s leaders really do have actually existing meritocracy perfected.
One interesting takeout here is that Wen’s family made an order of magnitude more money than either Bo’s or Xi’s, and that Xi’s made more money than Bo’s. That’s partly because he’s been around for longer, but there’s also a lesson here about rising quietly and marrying well: well for values of acumen rather than affection (Wen is supposedly not happy with his wife, the gemstone queen and main business brain of the family firm).
Annoyingly, people seem to have stopped following the money in favour of going with the censorship angle. You can see a good assessment of whether and how much the NYT has been blocked in China here. The annoying thing about it is that anyone thinks that ‘China blocks embarrassing story about top official’ is news. On the other hand, you could argue that it might have been difficult to make a large chunk of closely argued financial analysis about Wen Jiabao into global news without the censorship martyr angle.
