Some theories:
- Strip people of absolutely all rights, make them feel helpless. Later gradually restore some rights so that they feel like they've gained freedoms, but not all.
- Keep very low COVID numbers on paper, say the west is unsafe and ban travel, preventing the outflow of money from China to the west.
- Crush the economy and nationalize private companies even further than they are now. Perhaps even nationalize foreign companies that operate in China (see Russia).
