ubiquitin,
I thank you for going back and forth about taxation and healthcare with DrP. He is getting answers that are very close to what I have written but I simply do not have the patience to go back and forth.
My 2 cents are that the Government has an infinite ability to spend money that it does not have. It simply prints it.
When it does , it is called a deficit. The current deficit is 31 Trillion. If we wanted to pay it all off, the government could raise taxes on everyone this year to raise it. That would never be done, because it would cause the economy to tank, impoverish everybody and cause a civil war.
The standard options to pay for what the government spends are either raising taxes or let the deficit grow and hope that tax revenue will also grow without the need to raise taxes.
There is never a one to one relationship between new government spending and raising taxation.
