If you think about it, the farms in America were how people survived. Families would easily rear 10 kids to work the farm, but with the advent of African slavery, Whites could not compete. Whites in the South were piss poor, and jews lived fat off the hog. How could that be possible if White people owned the slaves? Jews cannot compete with White people. They have to have slaves in order to keep up. This is, in fact, why they're flooding America with non-Whites and fleecing all the jobs to places like India and China. There are more slaves in India right now than there were in the entire history of the Western Hemisphere. China itself is a slave state. Everyone there is enslaved by the state, and jews created the state.

Territorial Map: Ethnic Germans living inside Poland in 1937

The movement of the invasion of Poland follows the ethnic line closely.

Ancient Greeks arrived in Greece around 2300 BC, during the Early Helladic Period, according to data from this study: https://www.sciencedirect.com/science/article/pii/S0092867421003706

Greeks descend from Indo-Europeans of the Catacomb Culture, which was a direct successor of the Yamnaya culture.

The earliest Greek invaders were genetically similar to modern central Europeans, with around half Western Steppe Herder (PIE) ancestry.

However, by the Mycenaean age, it seems that ancient Greeks' WSH/PIE ancestry had been diluted significantly to around 10% on average. As per current evidence, modern Greeks have more WSH ancestry than Mycenaeans.

EDIT: By "ancient Greeks" I mean Greek-speaking Indo-Europeans who introduced Greek language and IE culture.
