The general view on Das Kapital today is that it's an interesting book for historical purposes, and got some things right, but also got a lot of other things very wrong (such as the labor theory of value). It's not actually a book on economics as much as it's 'political economy' and an attempt to describe the process of economic history in a Hegelian sense. Marx and/or Das Kapital is not taught in economics curriculum because Das Kapital didn't contribute meaningfully to modern economics, which is based around mathematical modeling and empirical evidence.
For those who want to talk about Marx, to erect statues in his memory or to defend him as a philosopher, it is high time to discover some intellectual integrity and face up to the crimes committed in his name. It is wrong to say, as one commonly hears in some circles, that his program of Communism was a good idea, but poorly implemented. On the contrary, it was a bad idea from the start and the brutality that always accompanied it was a consequence of its core character.
