This part is simply not true.

This part is.
The USSR was never institutionally racist. Russian chauvanism was still a thing in the USSR and that was relic of the Tsarist era that keeps on giving.
The USSR's repressions were not a cut and dry wealth transfer between ethnicities unlike the US policies.
At their worst in terms of American morality, institutionally targeted programs were to enforce political control and break nationalistic tendencies of ethnic groups.
The vast majority of the repressions in the USSR were a result of the explosive growth of productive forces. It's very hard to make the case for the USSR that the benefits of those productive forces inherently benefitted Russians over everyone else.
It's very easy to make the case in the US for white supremacy.
