The idea
Banks have been further and further de-regulated and we are becomming beholden to them -
Why is it important?
Example: we have to live somewhere, so we buy a house (it's cheaper than renting because of buy to let…), because the banks are not regulated to prevent lending people amounts they can't pay back, they borrow as much as they can, which pushes up prices, so we have to borrow more… etc.
