Will people be leaving the US in search of more economically stable places?

Is this logic correct? We have trillions of dollars in debt. It is not sustainable like this. At some point, we will either have to have horrific inflation or go bankrupt. Right now we're just waiting for it to happen. Whether it is 5, 10, 15, or 50 years from now, so kind of major blow is coming. Should people be thinking now of other nations to live in and raise their children in before US prosperity becomes a thing of the past? How is Austrailia's economic situation? How difficult is it to learn Japanese and is there any place there that is not prone to earthquakes?
