According to his calculations, it would cut the S&P 500 Index in half, to 1212, and the blue-chip Dow Jones Industrial Average would collapse to 10,837. Paul noted that there's a lot of chaos in Washington right now, with an "unpredictable president" and those who are inclined to "tear him apart" but if the market takes that big of a tumble, he doesn't see it as Trump's fault.

"It's all man-made. It's not the fault of Donald Trump in the last week. If the market crashes tomorrow and we have a great depression, he didn't do it in six months. It took more like six or ten years to cause all these problems that we're facing," he said.

Stocks will try to bounce back on Monday from multiple losing weeks in a row. The Nasdaq just saw its fourth consecutive week of losses. Meanwhile, the Dow & S&P 500's losing streak now sits at two weeks. If Paul's vision is right, the damage is bound to worsen. "I see the foundation of our system built on sand, and a big wind comes along to blow it down," Paul said.
