John,
I don't think you're being quite honest, or clear, or perhaps you don't know, about the banking crisis. You've pin-pointed a lot of greed and nasty doings, but that doesn't explain why they were allowed to happen in the first place, and it doesn't explain what will happen now.
:o Allow me to challenge you: all of our money (98%) is created by banks from nothing, literally the tapping of a keyboard, and issued as loans (debt).
This means that no matter how much money we have in the economy, there is always money leaking out in terms of debt repayments, and the value of that money is eroded by inflation. So, more money has to be brought into the economy so that there's money to pay the debts, keep things going and deal with the inflation.i.e there has to be more borrowing; people have to be given every opportunity to borrow.
We get ourselves into a cycle. However, finding people/companies to keep on getting into debt so this upward spiral can continue is difficult. The fact that banks were lending to the very poor is a sign not only of greed and stupidity, but that nearly everyone else had had enough debt as they were prepared to take on. And the system needs more and more people to take on debt. So the banks looked for a group that would take on debt - the poor.
When the subprime market started to collapse it was a sign that the money supply was going to start shrinking. This means that we'd be poorer and we'd still have debt round our necks, so banks started to hoarde and wait for the bad news - who had made so many bad loans they'd go bust. (Truth is, when the money supply starts to shrink good loans turn to bad loans, so the banks, by freezing credit just accelerated the process of crisis and recession.)
As you know, as the money supply falls, people, lose jobs, debts can't be paid and we go into a Depression. The only thing that has prevented that so far is unprecedented government action. In the UK almost 1/3 of tax receipts have disappeared! So, we're borrowing (180 billion a year) just to standstill.
We will pay higher taxes, have less services and have poorer jobs to pay for debts created by the banking system; we have to borrow to have money in the economy (That's the way it works, even if you personally haven't borrowed yourself). We'll be debt slaves ultimately, and as things stand, the vast majority of us will be in that category, and our children. All for the banking system and who it benefits.
Your book doesn't tackle this. Are you worried you'll be called a Marxist?
