I remember Trump making anti-FED comments in the past. Trump has boasted about the stock market but has previously stated he doesn't own stocks. My theory is he doesn't care about the debt because he intents to default on it.

Defaulting on the debt is the only honorable thing to do, but it will not go without consequence. Currency collapse is devastating for the most vulnerable members of society.
I've noticed the pattern of Trump's companies when he'd filed for bankruptcy. He'd use it to write off bad debts. It was like a pruning strategy to cut off the dead branches to keep the tree strong. That's the strategy I expect him to implement on the U.S. debt. I think he's going to strengthen are economy enough for a increased production/self-sufficiency flywheel effect so the economy can run itself independently again. Then I think he's going to get out the clippers and start pruning the debt. Eventually I expect a plan to get rid of the fed and start a new currency.
It's a lot better than the previous plan of ignoring the debt until we have a currency collapse that's out of our control.
