This reserve army of labour fight among themselves for scarce jobs at lower and lower wages. At first glance, unemployment seems inefficient since unemployed workers do not increase profits, but unemployment is profitable within the global capitalist system because unemployment lowers wages which are costs from the perspective of the owners. From this perspective low wages benefit the system by reducing economic rents. Yet, it does not benefit workers; according to Karl Marx, the workers (proletariat) work to benefit the bourgeoisie through their production of capital. Capitalist systems unfairly manipulate the market for labour by perpetuating unemployment which lowers laborers demands for fair wages. Workers are pitted against one another at the service of increasing profits for owners. As a result of the capitalist mode of production, Marx argued that workers experienced alienation and estrangement through their economic identity. According to Marx, the only way to permanently eliminate unemployment would be to abolish capitalism and the system of forced competition for wages and then shift to a socialist or communist economic system. For contemporary Marxists, the existence of persistent unemployment is proof of the inability of capitalism to ensure full employment. Measurement
There are also different ways national statistical agencies measure unemployment. The differences may limit the validity of international comparisons of unemployment data. To some degree, the differences remain despite national statistical agencies increasingly adopting the definition of unemployment of the International Labour Organization.
However, the end of the recession was declared in January 2010 and unemployment peaked at nearly 2.7 million in 2011, appearing to ease fears of unemployment reaching 3 million. The unemployment rate of Britains young black people was 47.4% in 2011. 2013/2014 has seen the employment rate increase from 1,935,836 to 2,173,012 as supported by showing the UK is creating more job opportunities and forecasts the rate of increase in 2014/2015 will be another 7.2%.The 2008–2012 global recession has been called a "mancession" because of the disproportionate number of men who lost their jobs as compared to women. The gender gap became wide in the United States in 2009, when 10.5% of men in the labor force were unemployed, compared with 8% of women. Three quarters of the jobs that were lost in the recession in the US were held by men.A 26 April 2005 Asia Times article noted, "In regional giant South Africa, some 300,000 textile workers have lost their jobs in the past two years due to the influx of Chinese goods". The increasing US trade deficit with China cost 2.4 million American jobs between 2001–2008, according to a study by the Economic Policy Institute (EPI). From 2000–2007, the United States lost a total of 3.2 million manufacturing jobs. 12.1% of US military veterans who had served after the September 11 attacks in 2001 were unemployed as of 2011; 29.1% of male veterans aged 18–24 were unemployed. As of September 2016, the total veteran unemployment rate was 4.3 percent.
