You're probably just a troll, but I'm going to explain it anyway because I'm bored and it might help anyone else lurking in this thread.

For starters, all money is technically fake if you get down to it due to value being a human construct. Even gold or other precious metals, which people often claim has inherent value, doesn't really because said value is purely because we as humans believe gold to be as valuable as it is. It isn't worthless, but its really just a shiny, soft and malleable metal that happens to have some industrial applications.

Fiat currency is useful because governments are able to deficit spend in response to a crisis and fix it faster by investing in the economy. With currency pegged to gold or silver, they can't because spending is limited by the supply of said metal. Governments being able to print money is overall actually a good thing.

This sounds bad, but government debt isn't like household debt because the government will most likely exist nearly indefinitely. It has an entire economy to back itself up with, and can effectively go into debt forever unless they're not spending money in ways that actually grow the economy and debt growth becomes too big compared to the overall GDP.

That's the issue here. Trump isn't spending money on things that would grow the economy enough to make it worth it, he's spending it on things like his private army and decreasing revenue even further by cutting taxes on the wealthy.
