What lessons have Alex Knapp learned?

He is Outside the Beltway, and so am I. He cannot figure out why banking is so concentrated, but I notice that most of the debt is concentrated, in DC, as is the Fed. Quoting the quoter:

Robert Lenzer notes that the despite the hard lessons of 2008, the financial industry is still concentrated, meaning that the same systematic risks that led to the Financial Crisis are still with us.

All told, the 6 largest US financial institutions scrutinized by [Robert] Wilmers have 35% of all deposits and 53% of assets. The danger lies in their trading revenues, accomplished with borrowed funds, which amounted in 2010 to $56.1 billion- or 93% of ALL trading revenues by ALL banks.

I have a clue. Timmy announced the Socialist Banking Network, just a few weeks ago. Timmy intends the socialist banking network to be concentrated in Washington DC, and its sole purpose is to find suckers world wide willing to lend to the Congress. Don't blame the banks, blame the police power and the moral hazard of the US central government, banks really have no choice.
