An ill-advised trade war with China left the American empire in crisis. Desperate for more resources to fuel the growth of the Capitalist machine, the country returned to its roots, instigating a series of brutal expansionist wars in South America.
Now, with the region harshly depopulated, the country needs a new labor force to resume resource extraction. To encourage migration to the new US colonies, the government has revived the Homestead Act. Anyone who stakes a claim and defends it from the remaining resistance movements for five years is granted ownership of that land.
Go south! Ensure prosperity for you and your country. Settle for Biden!
I hate that this sounds so real.
