I agree with your solutions and consider that one aspect that will lead to the collapse is the fact that the government and its agencies are doing all they can to provide a facade of a strong economy as we continue to see low unemployment and GDP growth. The longer term consequence will be inflation that they are currently manipulation as well given the buying of assets to suppress interest rate and the manipulation of commodity prices. However, once other common input costs and wages demand start to increase, they will be little to stop inflation which will lead to higher rates and unsustainable fiscal debt levels that will force a global devaluation of fiat to be worth the paper it is printed on.
