Obama on How Markets Reduce Racial Discrimination


I like your answer much more. And just between us, when DeLong starts a sentence with, "The only answer I can think of..." I don't exactly lean forward in anticipation.
Oops I misread DeLong. I thought he was saying the U.S. government should become the world's largest private equity fund. But upon rereading that's not what he's saying. In fact, I think he's just repeating the "Dark Matter" argument?
Isn't that a little like an empire?
How would we protect our investments?
What if they refused to buy our goods?
Lots of questions.
El it is definitely an empire. For capital flows like those described to take place, people have to widely hold the view that the markets into which capital flows are at least as predictable as those from which it flows. All these heretofore lenders do not have adequate history with the rule of law for that to emerge, IMHO. So it would require external enforcement, aka empire.
I think lots of folks believe this is the efficient answer (US and UK becoming savers and seeking high returns where there is low hanging fruit) but the fact is nobody trusts any other economy to deal fairly with massive foreign capital investments. That distrust is probably the only thing propping up the dollar at this point.
It seems you had the advantage of having longer to think. I suspect he on reflection probably likes your answer. His own answer sounds like very wishful thinking to me.
