Compounding effects mean that success begets success.

The more successful you are, the more you are able to invest in the next round.

This means that even one lucky break can put you on a compounding trajectory to a 10x better outcome than before.

Imagine winning the lottery and now being on a permanently different strata.

If you can't save enough to have capital, then you'll just be on the wage treadmill.

The entire logic of society is based on this principle.
