ELI5: Why does US debt and deficit seem not big of a deal, but that of Greece and 3rd world countries does?

As a percent of GDP our debt is smaller than Greece's. We also have a much more diversified economy, more natural resources, and our citizens actually pay taxes.

We also have a couple advantages that are unique in the world, the biggest of which is that the US Dollar is the world's "reserve currency" meaning many international transactions take place in USD and all of these countries have a vested interest in a stable dollar.
