I’m back, relaxed, after the longest amount of time I’ve spent off-blog in three years. Trying to get back up to speed this morning, I noticed an interesting twist in the annals of bailed-out too-big-to-fail companies: RBS is being forced to sell some core assets, like its auto-insurance operations, which give stability to its earnings. At the same time, GM has managed to unsell Opel, an equally-core asset which had been going to Canada’s Magma Magna.
