Roll back is a term used to describe the act of reducing, lessening, skimping, lowering, returning, or decreasing something. It is often used in the context of policy or legislation, where a government or organization may roll back certain regulations or laws in order to make them less restrictive or more beneficial to the public. It can also be used in a more general sense, such as when a company rolls back prices on a product or service. In any case, the goal is to REDUCE the impact of the original policy or law and make it more favorable to the people it affects.
