1. is not true.
2. So much wrong with that guy's post, one doesn't know where to begin. The national debt has nothing to do with the things he said, the U.S. isn't collapsing under debt (deficits are too low, and the debt is not a problem at all at the present time), Trump's plan would drastically increase debt. Remember that the debt is the sum of deficits, and deficits are revenue minus spending. Trump is proposing drastic reductions in revenue and increases in spending. That's the opposite of what you want to do to reduce deficits. Further, his trade and immigration policy would be contractionary (probably lead to a self-induced recession), which would cause revenues to fall and automatic stabilizers to lead to higher spending. And finally, the way to reduce numerical debt (rather than debt burdens--not really important to me, but just so you know), is for the gov't to buy bonds on the secondary market and retire them. Trump has no plans to do that (and, good, as it would be stupid).
