J. Hobson 
Problems of Poverty (Routledge Revivals) [PDF ebook] 
An Inquiry into the Industrial Condition of the Poor

First published in 1891, this seminal work examines the primary causes of poverty during the industrial age. Through considering how poverty is measured, the growth of urbanisation and the supply of low-skilled labour in the workforce, Hobson arrives at possible solutions to the problem of poverty and explores the ethical issues surrounding it.
