This fellow in the image above has the right idea, but I have come up with a new slogan that I think is much more catchy. It’s an obvious play on Ronald Reagan’s infamous arch-conservative remark from yesteryear. Let’s make it go viral!
America is not the solution to the world’s problems. America IS the problem.
Proletarian Center for Research, Education and Culture 
Both good slogans, but your one is snappier!
Best wishes, Pete.

My opinion differs slightly: the desire to control others, usually through Capitalism, is the problem. The solution is compassion for all living beings.
