For Want of a Nail

For want of a nail the shoe was lost.

For want of a shoe, the horse was lost.

For want of a horse, the rider was lost.

For want of a rider, the message was lost.

For want of a message the battle was lost.

For want of a battle the kingdom was lost.

And for all for the want of a horseshoe nail.

For want of a nail, the tax code was lost – Forbes
