"the outcome is totally unpredictable."
In the case of mortgage flop the outcome was totally predictable (and even predicted by few wise men). The government built a classicpositive feedback scheme that could only function, because there was an abundance of cheap fiat money, printed by the government

"this country is so huge, we shouldn't even bother with trying to secure our borders."
The task of border security is absolutely trivial comparing with task of "regulating" the economy.

Lol, there is always 2 sides of every trade, and guess what? one of those sides is always right.

Michail, regulating banks in an an attempt to deter and prevent fraud and corruption is not the same as regulating the economy.

mathematics does not work in the markets in the real world?
wow, you should really tell that to all the hedge funds who pay mid-6digit salaries to all those math PhDs :)

they NEVER work perfectly in a classroom, that's the nature of stochastic.. wow.. maybe it's time for u to brush-up on your math-economics courses.
they can only predict with some % probability ..
and to be "right" in am trade you should only be right about 51% of the time.
however when you do macro-decision (like policies ) you can't afford to only be right 51% of the time.. besides out government is really not that smart.

I said as perfectly - since the classroom is a better controlled environment than the real world.

"out government is really not that smart."
The current ones are absolutely sure they are the smartest guys in the world. They have even 2 Nobel laureates in administration :-D

who are calling not that smart?? ^o) people who graduated from Harvard??!! (tr) but the less they do, the less chance there is to screw up for them.. isn't it also simple math? :-)

"but the less they do, the less chance there is to screw up for them.. "
Исключено. Им очень хочется порулить
