"We have a government that borrows $4 billion a day. We have a government that owes trillions of dollars in debt, half of that to foreigners, most of that to Chinese investors. I don't - that is extreme. Not only is it extreme. It's insane and it's unsustainable"

This quote by Marco Rubio is a stark reminder of the alarming monetary situation of the United States. He is mentioning that the US federal government is borrowing an astronomical quantity of cash every day, and has collected a massive quantity of financial obligation, with half of it owed to foreign investors, mainly from China. He is stressing that this is an extreme and unsustainable situation, which it is crazy for the United States to be in such a precarious monetary position. This quote acts as an alerting to the US government to take action and deal with the problem of its debt before it spirals out of control.
