I'd say that applies more to unions than it does in this case. It's possible the reductions in funding or a lack of funding increases could very well reverse the trend. But when it comes to funding and politics studies like this will always be used to 'prove' that the problem is 'solved' and that we no longer need to worry about it; therefore we can eliminate funding to the cause with no consequences. [ Of course, none of the politicians actually bothers to fund studies into whether or not the funding is needed to keep the trend from reversing. ]
