As Dr. Lieberman has pointed out, although more diplomatically, there hasn't been a whole hell of a lot of progress in the treatment of PD in the last 40 years. They found ldopa and everything froze in place until agonists came along as the patents on ldopa expired. In both cases we are a cash cow.

Treatments make money. Cures don't. Money/power is a fascinating subject. One of its truisms, going much farther back than Machiaveli's "The Prince", is that one may control power by channeling its flow to create bottlenecks. Once these points of concentration exist, simply controlling them controls the whole. That's why we have two political parties, three networks, one press feed, etc That's also why They are determined to control the Net.

In our case, it has been concentrate healing under the control of allopathic medicine, institute pharmacology as its base, install a system of hurdles that only Big Pharma can negotiate, and eliminate, by force if necessary, anyone who threatens that system.

The result is a rigid system where conformity is the norm, info spreads slowly against the barrier of tradition, treatments are common and cures rare, etc.
