But it starts a line of thought which carries us back through all of human history. Bill Whittle does an extraordinary job (as always) in explaining the importance of the 17th Amendment in the context of our nation's history and mankind's history.
In short, mankind's history is the story of the struggle and pain of change, for change always brings fear and uncertainty -- even real loss. But to cease to change is to die. That is why, for all their rallying cries for "CHANGE!" progressives always bring death. At the heart of their calls for "CHANGE!" is the desire to actually stop any change which they see as a threat to their own security or power.
The free market of a free people is the most changeable, fluid, spontaneous environment imaginable. It is fundamentally based on change. It cannot operate as a free market without the ability to radically, even painfully, change things, people, ideas, outcomes -- without answering to POWER.
To bring the inventiveness, initiative, self-expression, curiosity, imagination and spirit of a people to its knees in the name of "CHANGE!" requires a great deal of power. The power to punish and to reward, to control and to kill. The progressives' cry for "CHANGE!" is intended to destroy true change since it is always -- and only -- expressed through the power of government.
Here's my nutshell summation, for what it's worth.
Conservatives understand that principles are unchangeable, but that everything that exists because of those principles is constantly changing.
Liberals believe that principles are as changeable and fluid as the next guy's opinion, but that all the results that happen from this mishmash of "relativistic" values must be made UNchangeable.
Pick which one makes the most sense to you.
