The US government is in $30 trillion of debt. When there’s inflation, the value of each dollar decreases and debt becomes easier to pay off over time.
While I agree that inflation is understated, one simply cannot use mythical numbers as proof. The currency-issuing government never has to worry about paying its obligations that are denominated in its own currency and the "debt" is not a debt in the normal use of the term within the private sector.
The national debt is nothing more than a tracking number showing the balance of monetary assets left in the private sector after taxation destroys much of what the government spends. It is our net savings represented in Treasury obligations, not something we must (or even could) "pay off".
Doing so would amount to taxing all current dollars out of the system without spending any more to replace them, and we would still have foreign-owned Treasuries to deal with. In another word, default.
The government can only make money in 3 ways: taxes, creating more money, or issuing more bonds - going even further into debt.
There is only one way to create US dollars. Congress must spend them into existence. Taxation destroys dollars by applying them to the debt they were created from, making all federal spending new money creation. The difference is called "deficit" spending for the government, but it is the only net source of money the non-government sectors have.
Treasury bonds require existing dollars to purchase, so they are not a "funding" mechanism. Ditto for taxation, which is a reserve drain, not funding anything. The US dollar is self-funding by constitutional authority (Article 1: Section 8) anyway and needs no "funding".
The government devalues our money, spends more than they have, and then LIES to us about it.
As the monopoly issuer of our non-convertible fiat currency, our government neither has nor doesn't have money. It doesn't need it to "afford" anything that is for sale denominated in its own currency. Also, as long as resources potentially exist to consume the demand represented by currency created such money creation is not inflationary. It is only when resources and labor become scarce that prices are forced upward by additional demand.
