What's wrong with importing stuff? It's called global trade. There are countries willing to sell stuff to us for cheap in exchange for whatever goods and services we have to offer it's all fair game. Trump is trying to kill global trade, you must like him? Capitalism alone is unstable , you need central banks inject liquidity to boost demand in time of crisis like now.
Capitalism is the only system that rewards individual hard work; creates an efficient economy; and promotes and rewards innovation.
Politicians are irrelevant; I don't care about them. I only focus on policies. It doesn't matter who is in charge, all that matters is how you make your money.
Trading is good for everyone. I am all for it. Comparative advantage is key to creating an efficient global economy. But not the way we are doing it right now, and the reason that everything is cheap is because of monetary manipulation.
What is money?
It is an IOU.
What is its value?
I'm going to simplify things to get the point across, so let's say the market determines this- forex. Just like equities, money is traded. You look at the underlying economy of the country of origin. So $1 USD is valued more than $1 CAD, because the US goods in higher demand and there is a finite amount of USD available.
What's wrong with unlimited QE?
Peter Schiff used an excellent example in one of his recent podcast, do I will reuse the same. Say we have two farmers with equal amount of land. The land belonging to the first farmer is better suited to growing apples, so he does. The other farmer's land is better suited to growing oranges. After harvest, they barter their surplus (after personal consumption) so now each of them have both fruits. Swell!
The orange farmer decides to go on a vacation, so he can't produce oranges right now. So he instead creates an IOU and hands it to the apple farmer. The apple farmer "trusts" the paper for some future good and agrees to sell the orange farmer some of his surplus apples. On returning, the orange farmer realises that he can keep creating more IOUs and as long as the Apple farmer trusts his paper, he can continue to buy Apples for free! So now instead of growing oranges, he puts up a golf course on his land and earns rent.
It should become plainly obvious that in this scenario, the Apple farmer is at a loss. Those oranges are never coming. As soon as realises the deception, he can stop the trading.
In the US/Canada - China case it is something similar. Chinese banks accept USD and Treasuries for some future payment. But if the central banks keep printing IOUs without any real economy to back its value, people will see through the farce and the dollars will become useless. This could lead to a lot serious problems.
