Sorry
Suk, I couldn't resist throwing out a line.

Didn't mean to derail the discussion.
There are multiple facets. Part of the problem is inefficiency and a huge part is vested interest. Another area is prevention of costly events that unnecessarily burden the system. Some people believe they have the right to behave however they like as long as that behaviour doesn't adversely affect others. Unfortunately those behaviours can often lead to situations that do involve others as in vehicle accidents or shootings or even obesity. Even singular situations involve others when the behaviour takes away a family's income.
But, to me, the biggest part of the problem is the people behind the scenes lobbying to keep the status quo. If you are used to having your nose in the trough you aren't going to be impressed with someone reducing your swill. :asian:
