The deficit is essentially the difference between what the government spends and what it earns, kind of like when you spend more on avocado toast than you earn from your part-time job. The US government has been running deficits for years, and Peter Schiff thinks this will eventually lead to a debt crisis, where the country can't pay its bills. It's like having a maxed-out credit card, but instead of just cutting it up, the government just prints more money, which can lead to inflation!
The national debt is currently over $23 trillion, which is a number so big, it's hard to even comprehend – imagine a stack of $100 bills reaching the moon and back... twice! Peter Schiff believes that this debt will eventually become unsustainable, leading to a financial crisis that will make the 2008 recession look like a walk in the park. It's like playing a game of Jenga, where you keep adding blocks, but eventually, it all comes crashing down.
