Zero comprehension of $1 trillion

From Dallasnews.com:

"I don't know if I can conceive of what a trillion of anything might look like," said economist Dana Johnson of Comerica Inc. in Dallas, who gets paid to parse the big numbers. "These numbers are almost incomprehensible to the average person."

"The problem is that once we get into the 12-zero range, we just can't imagine what we're giving up," he said. "The usual graphics – piles of dollar bills bigger than the Rockies, etc. – may help a bit, but I think the real way to talk about it is to somehow describe what $1 trillion could actually buy."
