It won't be voluntary, we will be taxed and our government spends the money how they wish.
Our taxes are insufficient to pay for it. Instead the money will be printed (borrowed). Every 100 days we add a trillion dollars to the national debt. We are running annual budget deficits of close to $2 trillion. We are the world’s largest debtor nation.
"We will be taxed" no doubt. The US takes in $4.7 trillion of taxes. But then it spends $6.7 trillion. The extra $2 trillion is what supports the stuff Congress does to make themselves feel good and garner donations, things like protecting Ukraine's borders and the foreign aid laundromat ... and that money is created out of thin air - a credit entry inked on the balance sheet, "borrowed" from the "future".
But the "future" just pays interest and the now nearly $35 trillion U.S. debt never declines. The effect of creating new money is to dilute the value of everyone's cash. The GNP is $28 trillion one day, and $30 trillion the next, but the gross product of the nation hasn't changed a bit, there's just more dollars channeled into the money supply, paying for the pol's whims, pork, and boondoggles. Voila, 7% "inflation" (dilution) with the stroke of a pen.
Of course, the pols cheerleaders say that shows "the economy is GROWING!!, it's the biggest growth ever!! There's 30 bucks where there once was only 28!! This is the most robust economy ever!!". No, the amount of Product in the Nation is the same, it just costs more money to buy a part of it. Money is diluted.
"Dilution"? Nah ... I know, let's call it "Inflation". That sounds cool; it sounds like we're gaining! Yeah, that's the ticket!
Weimar, anyone?
