Well i might have been a bit rash, and a marxist history framework can sure be useful if you look at social/economic history specifically and try to explain certain developments. The problem though is that it often has an ideological baggage that skews the truth to fit a certain narrative. All this is a bit off topic though
Edit:
@NinjaFletch
You make some valid points, and i'm not saying marxist historiography does not bring anything valuable to the table, but even looking away from any biases on part of the author it still has certain ideological bias in it's framework. Marxist history was originally used as a tool to bring about and foster revolutions, much like nationalist history in the 19th and 20th century was used to strengthen nationalism. It's also rather deterministic in it's approach. It has of course gone through some changes since then and as far as i know has largely been pushed aside by the Annales School.
Again, this is a bit of topic.
