Pogroms were definitely not a Soviet phenomenon. Many of the party leaders were Jewish. In that article, it shows that since 1947 no famines. I think the original post is making the argument that they started making progress later. 1950-1970 they really did make progress in almost every concretely measurable thing. USSR went tits up in the way that maybe a chilled out company (albeit with a weird corporate culture) would not compete well against a sweatshop with a culture of work hard, make money. The latter would just have more output, innovate quicker and maybe make a better product. But maybe also be better at cutting corners, or marketing or growing for the sake of growth like a cancer. I’m all over the place bc it’s a huge topic, but there is a reason why a lot of people miss the Soviet Union - and it’s not only because it was their youth.

Pogrom, meaning specifically persecution of Jewish communities, was not a Soviet phenomenon. Otherwise, there were a number of ethnic persecution campaigns in the USSR, with the Holodomor being the largest, but there were also many others. There were lots of people killed.
