The average American throws out 2.6 pounds of garbage per day. With 315 million of us, that's about 819 million pounds of trash per day. At 2.2 pounds per kilogram, that's 370,909,091 kilograms per day. Even if $1,000 doesn't buy that much by that time, I imagine $371 billion per day will still be worth something. And that's just in the US.
