I have encountered quotes similar to this one on the internet in the past few days, attributed to Karl Marx's mother and referring to him:
I wish you were more interested in accumulating capital instead of just writing about it. Maybe then you could stop asking me for it.
(Some examples I found online: No One Knows You Better Than Your Mother: Just Ask Karl Marx’s Mom, Unbiased America, Confessions of a secret Marxist).
In the process of looking for the source, I found that most places omit the last bit (
Maybe then you could stop asking me for it.), and others change the sentence as if she was talking about him ("I wish Karl were..."). The few places who cite the source refer to Intellectuals, by Paul Johnson. I have not found the primary source for it.
Did Marx's mother say anything of the like?
