Yes USA will start to save again instead of spend, when the money flow runs out. But the example is exactly like the one I gave you about a man overspending. Printing press changes nothing. You can't print goods. You can choose between inflation and other forms of taxation though.
Funny you said that you should view economy in an aggregate. In this case it actually makes sense. Yes a consumer might not burrow money from china. Instead what happens is they go to store, load up on chinese goods. And the dollars end up in China. And you end up with huge trade deficit and balance of payments deficit. USA owes China, and the money that they owe is mostly used to BUY consumer goods from China. That means financing consumption by burrowing from the chinese.
This setup also means USA will not suffer from inflation as goods are currently flowing in and dollars out. But what happens when this reverses? Decreased standard of living, as American no longer can get free goods and will instead have to produce things for the chinese.
But as I said, there will be less products in the USA and more dollars. Even if GDP would increase (very doubtful) - the gains would be flowing to China as exports. Not much good for USA's standard of living.
I'm going to attempt to explain this a different way, given that I may have have strayed from the initial discussion, mostly due to my responding to other posts. Sorry about that.
I don't view the economy in an aggregate, I was simply responding to a hypothetical. Imports equate to real benefits and exports equate to real costs. Trade deficits vastly improve our standard of living. People mistakenly blame imports for the loss of jobs when, in point of fact, jobs are lost because taxes are too high for a given level of government spending.
Basically, at the end of the day, working to produce real goods and services for someone else to consume doesn't have a net economic benefit, unless we get to consume the real goods and services others produce in return. Our real wealth is the following: all we produce and keep for ourselves, imports, minus out exports.
Our current trade gap is simply a reflection of the rest of the world’s ultimate desire to save in the form US financial assets. The only possibly way for the foreign sector to accomplish this is in the form of financial assets, such as securities, cash, stocks, mutual funds, etc. Our trade deficit has nothing to do with us being dependent on borrowing from China or any other country, as most talk show ideologues crow on about. To meet their needs for savings, foreigners literally compete like crazy to sell their products ans services in the US. They even suppress their own domestic wages and consumption to obtain an absolute advantage. In the event these countries no longer want to hold US dollars, they will either spend those dollars, which will ultimately result in a more balanced trade position between the US and the foreign sector. Obviously, while this can affect foreign currency exchange markets, it won't result in some financial catastrophe for the United States.
Therefore, in my opinion, there really isn't a jobs problem. A responsible fiscal policy will always result in Americans having plenty of spending power to purchase any goods and services from the foreign sector and obtain full employment. A responsible fiscal policy will maximize our employment, output and out standard of living, regardless of any trade deficit.
First of all MV=PQ unnecessarily complicates simple demand and supply in this case. You must also remember that it only takes value additions to account (which funnily enough can be generated by inflation). Second I beleve that the prices are not raising faster because there should have been a lot of deflation. In other words the monetary base has grown, but the aggregate supply has grown a lot less.
In any case the velocity goes up if inflation goes up.
The ability to print money does not change anything in this scenario, as I already pointed out. USA will still be going from debt taker to debt payer. Which would not typically be a problem, if the money was not spent on consumption or if the deficits and the rate of them weren't one of their kind.
I was simply pointing out the obvious problems with the QTM identity. My point is, it's not as static or linear as some people make it out to be. In other words, an increase in the money supply doesn't necessarily cause inflation, and as you pointed out, can even be deflationary.
