From a nazi point of view Slavs weren’t white and since discrimination against people rendered by others as Slavs (or substitute terms “low wage polish laborers”) including polish people didn’t stop after the Red Army freed us from the shackles of Nazi Fascism there is still discrimination ongoing. This means that there is sense to the classification as “similar experiences to…” as someone who was in the ‘othered’ group, even though the classification in the first place didn’t make sense and was just used for evil goals.

Naturally this intersects with capitalism. The migrant workers with their low wages are often cast aside from bourgeois society. After the so called reunification and fall of real existing socialism the people in the “developed” (read political economic strong) Western Germany were importing humans as laborers, often just across the border, Polish, from Turkey, etc. which contributed to repression against those groups (cause capitalism, low wages, value etc.). In the meantime there were pogroms against “Vietnamese” migrant workers who were partially deported.
