the majority can't be trusted to come up with the "right" answer.

Of course they can come up with the right answer, if proper attention is paid to implementing and preserving the system. The US system is best for preserving individual liberty. The British/Canadian/Australian etc etc is the best for domestic peace order and good government.

It is when the system is ignored that the problems occur.

How did the the USA come to point where oaths to obey the Constitution and mottoes like "give me liberty or give me death" are erased by "the Islamic boogie man is lurking under your bed. Be afraid, be very afraid. Only high oil prices, unfettered cronyism and an all powerful Executive Branch can save you."
