The Jews created this hellscape through their endless wars and central banking. With firm control they manipulate and create this world.

And the races of men who are the subject of this Usury grow stronger, because they have survived this hellish battlefield the Jews created.

So they grow strong, while the Jews grow weak. You will never see a Jew athlete, only a Jew Politician and a Jew banker - trades where dishonesty is the primary skillset.

This hell they create, it only serves to lower their own status. The crucible creates betters all around them, out of abused and enslaved, deceived people, who were already their betters before the workout.
