I was wrong about Trump (Ad)

I made a mistake. A mistake I feel very foolish about. After speaking with Donald Trump and some of his advisors, I believed him. I believed the promise that he would finally confront the single most dangerous threat to American life. That he would fix the ticking time bomb I’ve been warning about for 15 years. But I was wrong.

Let me show you exactly what we’re doing to prepare.

Fine. Don’t believe me. (Ad)

They called me an alarmist... When in 2010 I said America’s debt was out of control. When I warned it would unleash a wave of civil unrest, society collapse, inflation, and currency debasement, they called me crazy. When I said the dollar’s reign was coming to an end… that interest payments would one day overwhelm our budget… they said: that’ll never happen here. And yet – here we are. America’s national debt just blew past $37 trillion.

Go here and let me explain everything.
