Is America being selfish?

I thought it was time for rant, but I was so down about Americas attitude towards climate change and the Kyoto agreement, and hearing the news today about their attitude to Browns proposal for debt relief and the G8 just made want to scream. Is it an attitude held just at the top of government or is it a widely held protectionist position arising from the masses. The few Americans I know are as concerned about debt in Africa as many of my UK friends but what is the groundswell opinion. Has consumerism pervaded so deeply that now it is translated into what I can only describe as an overt SELFISHNESS that seems to be the motivating factor and attitude the white house holds as a plumbline when deciding on most issues but particularly towards debt and climate control.
