Jubilee (Bibilical):   the Year of Jubilee is a special year for the remission of sins and universal pardon where debts are forgiven, slaves and prisoners freed, and the mercies of God would be particularly manifest. In the Old Testament book of Leviticus, a Jubilee year is to occur every forty-nine years (seven times seven).

Every 49 years, everybody goes back to square-one and they start over again on a level playing field.
