The Omnibus Budget Reconciliation Act (OBRA) refers to a significant piece of legislation enacted in 1981 that aimed to reduce federal spending and reshape social programs. This act was a major legislative achievement of the Reagan administration, reflecting the rise of conservatism by advocating for tax cuts, deregulation, and a shift towards a smaller government. It sought to curb the growing deficit while simultaneously appealing to conservative ideals of fiscal responsibility and limited government intervention in the economy.
