how to affect policy change in america

I seem to recall waaaay back during the anti-war demonstrations of the 1960s and early ’70s that, while Dick Gregory praised the demonstrators’ intentions, he said that they would have little effect on America’s involvement in Viet Nam.

He said (and this is from memory) that if we REALLY want to make a change, we have to do it with our spending. For example, if every American refused to buy a Coca Cola or got to McDonalds for one week, Coca Cola and McDonalds would see that the war ended the following week.

I may be simplifying his argument, but you get the point. Of course, We didn’t do it for that war and we won’t do it for this war (these wars) . . .

Comments and arguments welcome!
