The US Dollar has been the standard since world war 2. And the way we are handling our economy is hurting that standard. Our economy is shit because we have a government that's more about milking the people with higher health insurance than building up our economy. China on the other hand is growing at rates that the US or any other country has never seen. Because of their growth, the cost of construction material has grown world wide.

Carbon is not the problem, it makes up 0.041% of our atmosphere , 95% of that is from Volcanos and decomposing plants and stuff. So people in the US are responsible for 13% of the carbon in the atmosphere which 95% is not from Humans, like cars and trucks and stuff and they want to spend trillions to fix it while Solar Panel plants are powered by coal plants
think about that
