Well I live in The Netherlands and somehow I trust the Dutch police to only enter my house for a valid reason, unfortunately I can't say the same for Google/NSA reading my emails.
It's not for the money, I can think of more effective ways I can spend my time to save money. My reason is that I don't like the feeling of having these very personal conversations being stored on the harddisks of google. I might trust google right now with my email but when I no longer do they will still have those files and there will be nothing I can do to completely make sure they delete them.
