Thinking about of the impossible is that, even if you stay in the planet for about a thousand year, the Debt of every country will never be payed off. Hence, it will just continue to grow. The current economy of every country doesn't knows that well. And by just a simple thinking, We should have a restart on everything.
Imagine this, you're just sleeping on your bed all day but you're debt on the government is not sleeping instead it keeps on rising every second. Such an unfair situation in life of every single person.
It's the nature of how the government run the country. No matter how big the debt our country has, as long as it is used for the betterment of the economy then we should be happy about it.
