One viewer wrote that America should build a "high-speed monorail" connecting all the state capitals. PBS asked Petra Todorovich, director of America 2050, to respond:
"High-speed rail is a great idea to connect the major cities of our nation's megaregions. Our country is going to add 100 million additional people by 2050, and yet we have no infrastructure plan or growth strategy to accomodate those people."
Another viewer suggests that America needs to rebuild its manufacturing economy.
