Why should Musk or any other rich person pay off the government's debts? In essence, debt is the result of poor financial management, only at the state level, these are the mistakes of the government, not individuals. And those people who managed to make a fortune know how to manage money and worked very hard to achieve this, and they did not achieve this in order to ultimately pay off someone else's debts, much less the government's. It's like your neighbor coming to you and asking you to pay off his loan because you are a wealthy person and he is poor, but it doesn't work that way.
Nevertheless most of those rich people benefit more from government. They are made rich by government support through cronies in government because they get private information on government propose capital projects which they made themselves available to get some of those contracts, they register companies that will get those contracts. Rich people are supported to get huge loans to run business and tasked lower or given task wavers so that they can build the business.
There so much secret deals going on with rich people and those in government, so their growth is also supported by the government personnels.
Trump is promising to support Elon musk in this trying times. He is promising to buy Tesla cars and that I suppose is from government. So they make policy to favour rich friends too, they should support the country when they are called to help.
There is no denying that the rich are getting support and favors from the government but in return, they also help the government every day by creating more jobs and bringing huge tax revenue to the government. Isn't that their payback to the government? Isn't that enough?
The rich will never receive any help or favor without benefiting the government, and this is a win-win cooperation.
Also, using the money of the rich to pay off the national debt. Is that an effective solution to completely solve the problem when the root cause of public debt is poor financial management by the government?
If the government wants to pay off the national debt, it should find ways to stop the debt from growing before thinking about paying it off.
By the way, without Elon's strong support, would Trump and the Republicans have a chance to take over the White House?
