The left don't think that trauma can be inherited. They think that wealth and social standing can. If your parents have money they can use their wealth to make it easier for you to have money

If your parents are poor (perhaps due to racism) then you will live in a poor area with worse schools, possibly contaminated with pollution, subject to higher insurance and basic costs.

This doesn't require magic ancestral memories it just requires ecomonics.

Well, some of them do, as otherwise they would not have told me about it at length in conversation. Scientific literacy varies greatly within every political camp.

I don't know if you can speak for the entire left here, it's really not hard to find articles from the 2010s from otherwise fairly respectable progressive publications which are pretty confident. Usually when I've heard ideologically minded people talking about "transgenerational trauma" [1], it's from a lens of epigenics. I don't think anyone would reasonably doubt that wealth or poverty ripples through many generations, the idea which I hear touted pretty frequently (and is discussed in the article), is that past trauma from war, famine, racism, etc. has a biological mechanism which explains disparities we see today.

As others have pointed out, it's a super convenient conclusion for folks who seek to understand the world in such a way, but at least presently the data just isn't there.

The epigenetic reaction to trauma is something that may be able to be inherited.

(Not trying to pose this as a left/right thing - but rather "this is a thing" - and these aren't memories but rather the result of epigenetic changes to the expression of hormones and neurotransmitters that may be able to be passed from mother to child and exhibit differences in how one reacts to certain stimuli)
