To Zakaria, the main challenges that face the US have to do with creating and maintaining conditions that will allow the US economy to grow. Zakaria argues that the "rise of the rest" can be a good thing for the US economy, but only if the US is ready for it.
What that means is that the US needs to have a system of education and training that prepares Americans to be innovators. It also means that the US needs the infrastructure that will allow innovation to happen. Finally, it means that the US needs to have an immigration policy that allows more people to enter the country who would bring the skills that we need.
Today, Zakaria also argues that the US needs political reform. He says that America's politicians are unable to do what is needed to deal with issues like the government deficit and debt and with issues like immigration.
