Richard Heinberg has a nice piece about drawing conclusions from present trends. Among his observations:
If current economic trends continue . . .
China's economy will be 8 times as big as it is today by 2040.
China's economy will surpass the size of the present global economy before 2050.
The US federal debt will double--from $14 trillion to $28 trillion--by 2022.
In 2072, the federal debt will amount to $896 trillion, or $1,629,091 for each American (assuming a US population then of 550 million).
By the end of the century, each American will "owe" over a billion dollars.
