No, that's inflation adjusted.

If I ignored inflation it would be eight month's wages.

This is the thing, no. _Even adjusted for inflation_, the pre-industrial working class (and the early-to-mid-industrial working class, for that matter) was paid barely anything. This was recognised as a problem at the time, even; a lot of the push for the reform of the Corn Laws in Britain, say, came from capitalists, who were, rightly, concerned that the working class _couldn't actually afford to buy any of their products_ (this largely played out; once they were repealed, living costs fell, wages rose, and the consumer market expanded greatly).
