IF? WHY?

If we 'lend' the banks £50 billion, can they lend out, through the magic of fractional reserve banking, £500 billion?

Do we borrow from banks for public sector finance, when we can create £50 billion to 'lend' to banks so they can lend that to the general public?

If either of these is true, this country, and in particular Members of Parliament, have totally lost the plot.
