Most Americans don't understand the Debt Ceiling at all: Because if they really did they would be very worried like those of us that do

 However, it’s likely that many Americans don’t understand what the debt ceiling is or what raising it entails. Consider the high share of respondents who said they were unsure in The Economist/YouGov’s survey. Part of what’s tricky here is the debt ceiling refers to debt and financial obligations the U.S. has already accrued — such as interest on the country’s debt or previously authorized spending, like Social Security benefits. That is, the debt limit is not a tool that authorizes new spending, as such expenditures are decided in completely separate legislation, like a bill for the next federal budget.

The problems with the debt ceiling have to do with we are borrowing more money than the economy can presently sustain in the long run and at some point the U.S. might go bankrupt from doing this through the Viet Nam War, The Iraq and Afghan wars now since the early 2000s. So, because of these wars cost trillions of dollars and because we haven't had an infrastructure bill pass since Eisenhower, we are infrastructure wise in terrible shape regarding roads, bridges, and natural Gas mains as they blow up houses and other mains one by one around the country killing people because most of the gas mains now are 50 to 75 years old or older. And when they are not replaced soon enough people die. The same is true of rusty bridges that kill people when they fall down often too around the country one by one.
