Monetary inflation absolutely causes currency devaluation. Not to be confused with money, currency is simply a receipt for money. Which is a store of value. If you take away the store of value, which we have, all you have left are receipts good only in confidence of the producers of the receipts. In this case, govt (like almost all fiat currency in history). The more of them they "print", the more in rotation and the less they are worth.
Increasing spending, being that we are already borrowing money, on interest, to spend, would mean that in order for govt. to spend, they need to borrow that money, on interest. This is artificial demand for both currency and products. And it ends with us right back here saying we nned to inject, yet again, more money. This is beyond ridiculous as a fiscal policy for any home, or any government. Government must cut its spending severely to match its revenue and then get the fuck out of the way and allow the producers to create wealth again. At least before the fed steps in and inflates that wealth away.
You know, savings. I know, I know. What a concept!!
