Yes, China has gone from near the bottom to the second largest economy in the world, but this is despite the Supreme Leaders, not because of them. If you want to know where the Chinese people would be without the CCP and their Supreme Leaders, look at Taiwan, or Hong Kong before the handover.

If our leaders stuff up badly enough, we replace them after four years. What can China do when, for example, the Supreme Leader starves 40 million to death in a Great Leap Forward, or sets back the country's development by decades through Cultural Revolution, or destroys the country's long term future by excessive and now irreversible population control, or trashes the economy trying to eradicate a virus? Answer: 0.
