Deficiencies in the current U.S. political ecology make it difficult for the efficient administration of the federal government, so the national economic development derails from the right track…Massive tax cuts directly reduce the federal government’s sources of debt repayment, therefore further weakens the base of government’s debt repayment…..The virtual solvency of the federal government would be likely to become the detonator of the next financial crisis….The market’s reversing recognition of the value of U.S. Treasury bonds and U.S. dollar will be a powerful force in destroying the fragile debt chain of the federal government.  ~China’s Dagong Global Credit Rating Co on dropping US Treasury rating to BBB+ from A- in January 2018
