Because you're talking rubbish?
You said,"There are better ways to lead a change than going to war. At this point we cannot afford the destruction of property because rebuilding will require even more resources."
Where did I say we must go to war? And where did I say that we must destroy property?
What I am saying is that if we don't stop living with as little as possible, and if we don't shopping, and if we don't stop producing things that are needed and whose toxic residue is polluting the earth, we are going to be extinct soon.
If enough people (ordinary citizens) do that, this will begin to effect the profits of businesses and some will go out of business, and that is what we want. It's not the essential businesses that will disappear but the ones where people don't really need their products - the ones we do without.
Next, I'm not American, and while I've lived in America (11 years), America is not the entire world, and what may apply to America does not necessarily apply to the entire world. What applies to the entire world is that we have to cut down on our manufacturing and learn to live smaller.
You're wrong that capitalism can't be stopped. Like I said, give it another 5 years - when you've had a major city or two burn to the ground, when millions of people have died in floods, etc. Then watch how quickly businesses die.
