Not sure TFA supports your assertion that he was a socialist.
The principles for Neals Yard regarding worker involvement, favouring encouraging and supporting workers expanding businesses by starting their own offshoots, and his practice of giving away businesses does smell lightly of something close-ish to socialism, though perhaps closer to the kind of Owens and Fourier, that Marx came to describe as "utopian" for their failure to provide any answers for society-wide structural change, than any more modern version.
As another comments pointed out, this article is peak Guardian - favouring small businesses and artisanal products over mass production, and countering extremes of capitalism in eccentric small scale ways, while at no point favouring anything to effect actual lasting change in any way that might threaten anyone with money.
Did something in the article or Saunders’ life point to him being neoliberal or into eugenics?
Your comment is strange; I assume you would not like it if people applied the sins of your father to you. If anything, the fact that Saunders turned out the way he did despite his father should be a cause for celebration.
Your comment made me sad that you thought a clearly positive-sum person’s life story could be summed up so pithely.
(I don't know anything about his father. If anything, he might have been more egalitarian, after all neoliberal economics is about businesses serving everyone.)
And yeah, it is a wonderful story despite that. Comments don't have to sum up the story.
The big 'life lesson' you learn if you study counterculture is that pretty much every big counterculture figure was a 'trustafarian' or from - at the very least - a tidy upper-ish middle class family.
