If you skinned and sold squirrels at a rate of 7.56 squirrels per second, you'd reach his wealth in just 100 years! All it takes is a little hard work!
They'd also go extinct after 1 year. Maybe switch to rats.
Oh, you actually shared the median. The average is $1.06 million. I guess I know some broke-ass people, and am one myself. Almost everyone I know is well below those numbers.
