-Show with the shutdown that departments still ran well with minimal staffing as incredibly slashed government spending will be necessary.
-Run up the debt and spend on your credit cards as much as possible, while you can, atleast until some infrastructure/walls are built.
-Default on the debt/gold back the USD.
-Live within means.

Just a guess… can it be done with the unfunded liabilities is a question I have. I think the man has a plan….
