I do agree with the argument of the text, but I don't think it is a good introductory read for someone who doesn't already have an understanding of how historical materialism works.

I would recommend this video first since it explains a lot of the same material, along with the general basics of historical materialism, and does so in terms that should be much more familiar to someone with a more mainstream understanding of politics: https://www.youtube.com/watch?v=9nPVkpWMH9k
