-
and that new allocation can't be better than the original one.

No matter what the government does in the end
-
the upshot is a new allocation X^-hat, Y^.
-
We don't have to think about it got there.
-
That's where it got
-
and according to this argument it can't be better.
-
So the argument is correct and elegant.
-
There must be something missing to the argument,
-
some assumption you don't really believe if you doubt the argument.
