For decades, China’s business class had an unspoken contract with the Communist Party: Let us make money and we’ll turn a blind eye to how you use your power.

Like most Chinese people, they bought into the party’s argument that its one-party rule provides more efficient governance.

Now, the tacit agreement that entrepreneurs had come to count on is dissolving in front of their eyes. China’s leader, Xi Jinping, used an important Communist Party congress last month to establish near-absolute power and make it clear that security would trump the economy as the nation’s priority.
