Why has the US stopped investing in itself? Why do things—from cell phones to highways to schools to trains—work better in countries that used to look to the US as their model?  We speak with Christine Loh who is a Hong Kong-based academic, environmentalist, and former government official with deep ties to the United States. Her conversation with Alan Stoga raises questions about how and if the country can recover its dynamism.  Not to be trite or political but can America be great again?
