In January this year, when Bob Diamond opined that the time for "remorse and apology" by banks over their role in the financial crisis should end, some people were listening more closely than others. Two purported Wall Street financiers have taken up the cause in cyberspace, rapping on YouTube in defence of people like Bob. Dubbing themselves Leeman Brothaz the duo argue that Wall Street greed was not to blame for the crisis as it helped the "corporate drones" take "neg am loans" to buy some "sick-ass homes". Not many rappers spend time rhyming "credit default swaps" with "were bought by wealthy WASPs" so the song is something of a departure for the genre. But its conclusion that "greed is good" is surely one thing that Diamond and other bonus-laden bank chief executives can agree on.
