People have seen that there's a lot you can do to make the problem better without bankrupting people. That's what it's all about. We like to think of it as an issue of trade-offs that people face. There is always the potential for things to get worse. But if that happens, there are real consequences.
People get sick, people die.
There are huge losses to society and a lot of our work with our colleagues in developing countries has been in trying, in a systematic and hopefully quantified way, to point that out. It's not a nuisance. It's a huge cost to you, economically and in human life, and so you have it within your power, at reasonable cost, to get this problem down very, very substantially to at least keep it constant, instead of letting it grow, without bankrupting yourself. And to us, when we looked at the costs, it seems reasonable. We see it as a question of trade-offs.
