However there are many disadvantages to having this inevitably proliferating division of labour.
Capitalist owners, ever-seeking to lower cost and increase profit, are always on the lookout for cheap labour. Workers, being so specialized in their work ironically become deskilled and are unable to move readily between positions. This makes them vulnerable as they can be easily replaced like the cogs in a great impersonal machine (Sernau, 2006)
When seeking out a comparative advantage, they also seek out child labour, depriving children of basic education. According to the UNICEF website, an estimated 158 million children aged 5-14 are engaged in child labour - one in six children in the world. They work in mines, with chemicals, with pesticides in agriculture or with dangerous machinery. They are often invisible, toiling in homes, workshops or plantations. What makes it even more difficult is that these children are burdened by their families to make money and often have a fatalist mindset. They only think of living for the day.

Karl Marx also stated that modern industrial workers in capitalist economies experience extensive alienation. Work which is meant to be ennobling and purposeful has become routine, deskilled, repetitive tasks on minute parts of products that meant nothing to them (Sernau, 2006). This can be illustrated by an incident in June 2008 in Tokyo. A distraught man, fearing losing his temp job in a small-town auto parts factory, went on a killing spree in one of the city’s busiest areas. This raised the plight of temp workers in Japan as the number of traditional “jobs for life” disappear (AFP, 2008). Jobs are not only alienating, but impermanent too.
Perhaps we can take a leaf out of Shell. Their efforts to manage their social impacts are highly publicised. Their oil and gas operations take them to various parts of the world, even to places with poor human rights records. But their actions are guided by their general business principles, which state that they “…conduct business as responsible corporate members of society, to comply with applicable laws and regulations, to support fundamental human rights in line with the legitimate role of business….”. For employees, Shell has direct responsibility for issues such as labour rights, working conditions and freedom from discrimination. They are also commited not to exploit children, through direct employment or indirectly through joint ventures, contractors or suppliers. According to their annual internal questionnaire of senior country representatives, at the end of 2007, Shell companies in 99% of countries where they operate had procedures to prevent child labour. In 98% of countries they also require their contractors to have a procedure in place to prevent child labour.
