Although Marxism is often accused of being class reductionist, Marxist theory accounts for oppression on
the working class based in gender or ethnicity however this marginalisation is
not seen as an individual stigma, but part of the superstructure of oppressive
institutions that form the superstructure of the economic base of capital. 

For
example, Marxist feminists such as Silvia Federici in the ‘Wages for housework’
campaign highlighting the unpaid reproductive labour of women and its place in
the process of bourgeois accumulation of capital. The autonomist Marxist works
of Federici seek to point out Marx’s failure to see the amount of unwaged and
unrecognised labour that goes into supporting the economic base of capital;
Work often historically undertaken by women, people of colour, the old and the
young.

In this way the criticisms of Marx as class
reductionist is unfair, to Marxists ‘identity politics’ exists as the
intersections between class and ethnicity, gender and social identity.  For example in Modern Britain there is often
a divide between the ethnicity of different workers on the shop floor, racism
and xenophobia often exists as social divisions between these workers, foremen and managers often use these divisions for their own gain. For example the racism faced by Eastern Eurpoean and Asian workers in the media and popular white ‘nativist’ discourses playing different ethnicity’s off against each other to reduce wages and workplace conditions.

For Marxists,
social identity, such as nationality, gender or ethnicity is not ignored but
recognised to help support the division of the labour that is forced by capitalism onto the proletariat.

This is so true and important
