Organized crime networks also like to hide behind shell companies, contractors and legitimate businesses.

Investigators use the concept of cui bono to figure out who is ultimately responsible.

Who benefits?

Just because local distributors are doing the bribing doesn't insulate the megacorp from moral culpability for their actions.

By the way, the bribes often aren't in cash, they're free cases of Coke.

True, but the real problem is obviously the money taken from Coca-Cola having a plant in Chiapas is not reaching the poorest inhabitants through urban planning/economic long term strategy and instead going into somebody's pocket. This is a political problem and nothing Coca-Cola can do will change that. Any attempt at companies getting involved in local activism will just put those people at even more risk. For the water problem they could attempt to fund the building of wells in these communities affected but this will of course be a corrupt money pit, tons will be spent and nothing done so really all they can do is leave the state, then Chiapas is even more poor and desperate.

So at what point does a megacorp, with all of its power and wealth, decide to do something good? Will we ever get to a point where we can we at least try to evolve towards sustainable capitalism?
