Equating bribery with tips?
Equating tips with bribes??? You've got to be kidding.
The service people who rely on tips to make ends meet, at least in Canada, have a lower minimum wage, by law, than other positions.
If you are not willing to tip, then don't use these services.
What's going on in Countries like India is a more life effecting situation. Here there is a choice to not, say, eat in a restaurant vs in India there seems to be little choice if you want, say, a birth certificate for your child you must pay a bribe to get it. These are by no means the same thing.
What I find interesting about this new project is that it is working on some, ( I would doubt all, given the variety of human nature.)
This says to me, that while bribery is systemic, all those who accept the bribes -- simply because this is how it's been done for decades/centuries -- can feel shame and are willing to make amends.
Human wonders never cease.
