"The more ANY Government takes out of any economy, the less there is for growth..."
jbazen, you've nailed it! There is ample evidence that the Laffer curve reflects reality, and Dan Mitchell has done a great job explaining it in recent articles.
But the simple fact is that government crowds out private sector economic activity. Imagine yourself on a desert island with 100 others, no contact with the outside world (no free lunch). How many people would you have in government, and how many would you prefer to be producing the "stuff" you need, housing, food, means of transportation, etc.? Why do we think government should be doing all the things the politicians want?
