Of course, that money is redeployed, which is good. The point is that, in the case of something like chronic pain, it is very difficult to measure the level of pain, but easy to measure the money spent on it. So, it can be challenging to compare.
Or, to go back to technology, take Facebook for example. Perhaps people would have liked to have a social networking site before, but it simply wasn't available. When it became available, many people used it and enjoyed it in their leisure time. Because it's free, and, while large, does not pull very large revenues per user, it doesn't show up as a major economic activity. And because it's used mostly as an end-consumer leisure activity, it is missed by indicators that don't measure this well. So there can be a substantial total increase in services enjoyed, and we might be missing it. Again - might. I cannot say for sure, but it's worth asking.
