It is true that almost all countries have experienced an increase in the amount of debt due to the unstoppable spread of the corona virus.
And the state must go into debt to save the economy, so it is true that increasing debt cannot be avoided. Without being indebted, the state
cannot provide assistance to its people who have lost their jobs, a big disaster that happened in 2020, indeed destroying the world economy.
Hopefully this COVID19 pandemic will end soon, so the national debt will not continue to increase.
Many countries are not really focusing on how big their debt it because people is more valuable than the country's economy, leaders are willing to accept that their country needs to be in debt in order to save its people and yes it is gonna be hard in the long run because the government will need to increase tax or anything in order to slowly pay their debt once this pandemic ends
Most nations do not care about the debt they are making and the printed money causing inflation, only because the other nations are doing it as well, that is the real reason. Not because they "have to" because they really do have to print money and make a debt and that is a reality but that is not the "reason" for it.
If it would cost the country a lot of money and would destroy everyone's financials, that would result with death as well, you probably are aware about the fact that if a nation becomes so poor that they can't even pay for food, eventually people die which would be even scarier than coronavirus, look at Venezuela for example. So, the reason why they were capable of printing money and making debt was the simple fact that all of the world was doing it, so they didn't got worse alone.
