spending and debts

I was talking to a relative the other day, and he is worried that China is buying up lots of properties in Canada. And I said, there's no problem in buying and selling. Just like, you sold me your car, and I gave you the money. The problem only arises if you spend it all on ice-cream. But if you spend it on education, then it's only fair.

So in the US, not only have they spent it on war machines, but they have also borrowed huge amounts of money from around the world, as if they are spending in advance at the expense of their future generations.

Then through Quantity Easing (QE), the US government succeeded in diluting all the loans!

From a critical analysis, the US has been riding on the sweats of the blacks and immigrants (some call it "internal colonization"), and then China, and now Vietnam, etc. The situation is somehow reversing, and contradictions are being imported back.
