Banker pay linked to asset returns?

Bank chief exec pay has soared from £1.5m in 1989 to £16m in 2011. A staggering rise. Yet if those numbers were related to the returns made on bank assets, that £16m figure would have just climbed to £2.1m. This calculation has been developed by Bank of England official Andrew Haldane. But would things really change? Especially when most banks can manipulate accounting information easily.
