444 billion seconds is 13950 years.
Seems like a lot and it is.
The current US debt is 36 trillion, in seconds that's 1.1 million years so even longer.
If every person of every age in the US were to give 1 dollar a second towards the debt, it would be about 100000 seconds, or just over a day to pay it off.
If we took every dime of every billionaire world wide and put it towards the debt, we would still need to give a dollar every second for like 16 hours.
At some point huge numbers really don't mean anything, they just get bigger but with no meaning. I am sure all the richest billionaires want to be the first trillionaire, same as when the millionaires wanted to be the first billionaire. I am sure all the billionaires don't really care if they get richer, they are so rich it just does not matter, again maybe being the first trillionaire.
