First make "right" easy then make "wrong" hard

I think it is best to make it easy to do the right thing and then make it hard to do the wrong thing.
Two examples:
The music industry should have made it wasy to buy and download legal music before making massive prosecutions. Most people will do the right thing when it is easy.
Immigration: We should make it easy to do the right thing (especially for those who aren't currently breaking the law) by making a guest worker program with generous limits, then after that is working well increase border security.
