the bankers were the only ones making us any money
Making money ? ........you sure you're not mixing up 'making' with 'taking' ?
Because only someone with a hopelessly romantic view of capitalism, would believe that bankers make money.
Bankers simply shuffle other people's money around the economy - whilst helping themselves and filling their own pockets. IE, they offer to look after your money, and then lend it to someone else ..... for a fee of course.
They don't actually make any money, and the whole business is based on the fact they don't have any money. That is why when there is a run on a bank and people ask for their money back, the consequences are so disastrous - they simply don't have the money to give back.
And ironically, it is the activities of the banks, which tend to devalue money. During periods of intense activity by the banking sector, ie boom periods, money devalues and inflation invariably occurs. Whilst during periods of little or no activity by the banks, ie when they won't lend, then there is a real risk of deflation as money increases in value.
The people who make the material wealth in a society, eg, your car, home, tv, etc, are the productive forces - without someone producing something somewhere, there can be no material wealth. They extract the raw materials which have no "practical" value, and through their labours, transform them into products with value.
And whether the productive forces are based in Coventry or Shanghai, makes no difference - they are still the ones which produce the material wealth in society.
This however, does not mean that bankers do not play an important and vital role. Indeed like other service industries, the financial institutions are hugely important in the smooth and effective running of the productive forces.
In fact they are so important to smooth and effective running of the productive forces, that they cannot simply be left to the whimsical fancies of the mythical laissez-faire free-market - and allowed to fail. This is why democratic control of the banks through common ownership is so important.
And why an arch right-wing neo-conservative such as George Bush, was prepared without a moment's hesitation, to carry out the wholesale nationalisation of US financial institutions. IIRC, the majority of mortgages in the US are now owned by the US government.
Live or die at the mercy of the free-market is not an option for banks.
