The U.S. government is $14.3 trillion in debt. When we first neared the trillion-dollar mark in 1981, President Ronald Reagan said that the height of our debt amounted to a stack of $1,000 bills about 67 miles high. That's somewhere in the thermosphere.
Today, that pile of $1,000 bills would be floating in space, more than 900 miles above the Earth. There aren't any $1,000 bills in circulation anymore, so here's an astronomical analogy about today's debt: If you stack up 14.3 trillion dollar bills, the pile would stretch to the moon and back twice.
