Problems with Compound Interest

A person loans $10,000 to a bank
for 10 years at 10% interest.
They would earn $1000 in interest each year.

If they spent the interest,
they would have only $10,000 at the end of ten years.
If they save the interest,
they would double their money in about seven years.

This makes it easy to save.

However, they can only add the interest to the money deposit in the bank
if the bank can lend the additional money to someone.
So people can only double their money every seven years by compounding interest
If the level of debt in society doubles at the same speed.
Compound interest produces an indebted society.

Compounding interest speeds the shift of wealth
from those who are indebted to those who have plenty.
