Rich people burn their carbon in China, where their factories are. Poor people burn it at home and where their jobs are.
The ultimate problem with carbon taxes is that they only apply to isolated open system, and encourage production to be moved to adjacent, but untaxed, systems. Hence, a regional carbon tax cannot really control global emission levels, but rather shift the cost of production around (as well as production centers). Its technocratic tinkering to an impending extinction.
