I think it’s pretty simple. To many people, $3,750 is a huge amount of money. It’s easily several months salary.

I think a lot of people would be relatively unaware of how illegal a given thing is and would instead see the amount of money being offered as representative of the risk. Too much and they would get suspicious.

The "kia boys" are out stealing car after car for $100 from interviews online.

Incentives seem lower than we all think?

I remember some very sad news about a drug smuggler, a poor woman from the Philippines, condemned to an insanely harsh sentence in Singapore (perhaps even death penalty?). At least, the UK justice system should be less cruel.
