As a workaround many policy makers try to restore competitiveness through internal devaluation, a painful economic adjustment process, where a country aims to reduce its unit labour costs. German economist Hans-Werner Sinn noted in 2012 that Ireland was the only country that had implemented relative wage moderation in the last five years, which helped decrease its relative price/wage levels by 16%. Greece would need to bring this figure down by 31%, effectively reaching the level of Turkey. By 2012, wages in Greece had been cut to a level last seen in the late 1990s. Purchasing power dropped even more to the level of 1986. Similarly, salaries in Italy fell to 1986 levels and consumption fell to the level of 1950.
