Six part series that is informative and very timely to what we are dealing with today. Incredibly from 1978.
Part 1 he describes a general trend of government taking over more and more over time. It's just what unchecked government does.
The first couple minutes of Part 2 describe exactly how this POS is happening. The urge to tap new funds for new programs is an incentive for politics and even special interest. But once government does a takeover, resources will diminish for current programs, moving on to new programs to take over.
What more can one really add to this? Other than everyone should watch this and nearly every other video Milton Friedman has out on a variety of subjects in economics/government.
