Adenauer's achievements include the establishment of a stable democracy in West Germany and a lasting reconciliation with France, culminating in the Élysée Treaty. His political commitment to the Western powers achieved full sovereignty for West Germany, which was formally laid down in the General Treaty, although there remained Allied restrictions concerning the status of a potentially reunited Germany and the state of emergency in West Germany. Adenauer firmly integrated the country with the emerging Euro-Atlantic community (NATO and the Organisation for European Economic Cooperation). Adenauer is closely linked to the implementation of an enhanced pension system, which ensured unparalleled prosperity for retired people. Along with his Minister for Economic Affairs and successor Ludwig Erhard, the West German model of a "social market economy" (a mixed economy with capitalism moderated by elements of social welfare and Catholic social teaching) allowed for the boom period known as the "Wirtschaftswunder" ("economic miracle") that produced broad prosperity. The Adenauer era witnessed a dramatic rise in the standard of living of average Germans, with real wages doubling between 1950 and 1963. This rising affluence was accompanied by a 20% fall in working hours during that same period, together with a fall in the unemployment rate from 8% in 1950 to 0.4% in 1965. in addition, an advanced welfare state was established.
