Yeah, it's weird. More separation of powers stuff. The intent is to be insulated from politics but not entirely divorced from the will of the people. As Calvin said, a good compromise leaves everyone mad.
That's exactly how we got here, in the precipice of a financial crisis that everyone is pretending not to see so we can keep the ponzi scheme running a bit more.
The people have no understanding of a lot of other stuff. That's why we use a REPRESENTATIVE democracy system, not a direct one. Is it perfect? not.
