The land you live on is owned by a single mega-corporation (they own 50,000 square kilometers of land around you). They act like a dictatorship. You were born on their land and are too poor to move anywhere. If you get too loud, the only local supermarket, owned by the corporation, raises the price of groceries just for you. So if your social credit score is too low, they will starve your family to death.

Oh, and also it rains acid so the plants are dead hehe
