There is an interesting post over at pieria.co.uk called "The Financialisation of Labour". Frances Coppola compares the changing economic incentives between a company making a capital investment in a slave and an employee. She then suggests replacing the word "slave" with the word "robot".

Interestingly, although Frances Coppola sees the structural problems in the labour market, she believes that companies potentially will be investing in both employees and robots, whereas I only see highly skilled people being employable in the future (with all the social problems that will bring).
