On one hand you have increasing immigration increasing the supply of labour. On the other hand, you have increasing automation reducing the demand for labour. And in the pinched middle you have falling wages. This cannot end well.

I don't know which is the most dangerous scenario: the working classes taking it out on immigrants, or the working classes making common cause with immigrant labour against a Victorian economy of squalor, ill-health and poverty (which is good, but dangerous it had to get to this point) and turning revolutionary. The latter is a failure of politics.
