The Cuban state asserts its adherence to socialist principles in organizing its largely state-controlled planned economy. Most of the means of production are owned and run by the government and most of the labor force is employed by the state. Recent years have seen a trend toward more private sector employment. By 2006, public sector employment was 78% and private sector 22%, compared to 91.8% to 8.2% in 1981. Government spending is 78.1% of GDP. Any firm that hires a Cuban must pay the Cuban government, which in turn pays the employee in Cuban pesos. The average monthly wage  is 466 Cuban pesos—about US$19. However, after an economic reform in January 2021, the minimum wage is about 2100 CUP (US$84) and the median wage is about 4000 CUP (US$166).
