You may have heard already that Finland is a country rather free of corruption in general. I have one anecdote that can support the view that it starts from society itself, and it all happened on Friday.
My wife dropped her mobile at the bus stop by mistake, and a person picked it up. The founder called me (being the last person she had called) and eventually he returned me the device. I actually tried to arrange the delivery by text message but the person never checked them, explaining that he wouldn't even open them as it was somebody else's mobile. I know for a fact that he never used it for anything else but calling me and and another person as I didn't answer his first call, and he would have been horrified if I had tried to offer him a reward for it.
I'm sure this wouldn't have happened in many places I know, and the fact that I know plenty of people who would have acted in the same way makes me feel more convinced to say that the fact there is little perceived corruption in this society because the people so demand.
When will we make other places change?
