UK's great financial sector?

We are often told how great our financial sector is, well that's blatantly not true, just have a look at this:

Of the G10 UK has by far the largest Financial debts. And note how small our government debts are!

The source of this debt arises from the banks having too much capital and too high leverage. The capital has been leeched out of people's pockets by mortgages, credit card loans and down right robbery of insurance savings. The leverage has been allowed to happen because of lack of government regulation.

Both these two causes have to be reversed.
