>I checked the actual numbers. The incarceration rate in the US is not 10x higher than the EU, it's only 7 to 8 times higher on average. (Maybe the poster meant that the incarceration rate is 10x higher than the incarceration rate in his particular nation?)

7 to 8 is as good as 10x.

Going from 1x to 8 is a huge 800% increase.

Whereas the correct 8 from the mentioned 10 is a mere 25% error...
