The reason Jews are pushing for open borders and diversity so much is because it reduces everyone's political power and makes the country easier to control. Diversity doesn't work and that is intentional. Groups stay divided socially and don't work together. The workplace is a microcosm of this. Studies have shown that diverse workplaces are far less likely to have the workers band together and unionize to fight for better conditions. They stay fractured into their own groups and are easier for the people in power to manipulate.

Weimar Germany failed because the Germans banded together around racial identity. For Weimar 2.0 to work they need to eliminate that possibility.
