Most economies have a fair amount of tax evasion, depending on how their data systems are.
If you turn a blind eye to fare evasion, if you accustom people to getting away with minor crime, you are making it more likely that they will go on to commit more serious crimes. That is why we have so much disorder in London. It is a disgrace.
