At present, financial crises occur, chiefly because the paper currency is redeemable in gold only.

Large sums were paid for the use of money, because the available amount of gold and silver was far less than was needed to carry on the commercial transactions of the times.

Not an old woman that buys a paper of pins, without yielding a part of the price to the banks as interest!

Accordingly, when the supply of gold runs short, the security behind the notes is diminished, the loaning of notes is restricted or suspended, and the panic follows.

Financial crises require governments.

Sometimes, instead of purchasing a commodity out and out, people want to buy only the use of it, for a longer or shorter period. The price paid for such temporary use is commonly called hire.
