Despite being well-known as the home to millionaires, many poor call cages home.

Anger over housing prices is a common theme in increasingly frequent antigovernmet protests. Legislator Frederick Fung warns there will be more if the problem can’t be solved. He compared the effect o the poor to a lab experiment.

“When we were in secondary school, we had some sort of experiment where we put many rats in a small box. They would bite each other,” said Fung. “When living spaces are so congested, they would make people feel uneasy, desperate,”and angry at the government, he said.
