What if a villain bought out the national debt? What would that mean? That's assuming he had enough money. I'm not sure how realistic that is, though. Could a corporation be big enough and have enough money to do that? Or maybe a bunch of corporations together?
In theory, yes. A corporation (or more likely a group of corporations or conglomerate) could put together the fourteen-trillion-plus dollars necessary to pay off the national debt.
However, based on what little I know about economics (which is almost nothing), this is more theoretical than practical. Most of the money a business takes in is essentially pre-spent on the expenses necessary to continually operate, such as supplies, shipping, marketing, paying their employees, taxes, and many many other things.
Simply earning USD $14+ trillion in profit over time wouldn't necessarily mean that a corporation has that much money to actually spend on new acquisitions, like the United States of America.
Of course, even if such a thing were to actually happen, I don't believe they'd actually own the government or the country in any technical sense...but I'm largely out of my element on the practical impact of what such a scenario would mean. Though presumably, most people would be similarly bewildered by the ramifications of such a thing - making it perfect for a plot in your game!
