Democracy is two wolves and a sheep voting on what's for dinner.
If you live in a society consisting of two wolves and a sheep, you have greater problems than a governmental system can fix.
I live in the Western World's Elective Dictatorship, par excellence. New Zealand has a unicameral Parliament, complete parliamentary sovereignty with no judicial review system, and no written constitution (we do have a very weak Bill of Rights that is solely a tool for interpretation). There is no external organisation like the EU to restrain lawmakers, and until the mid 1990s, we had First Past the Post on top of that.
Are there abuses? Yes. 1975-1993 was an interesting period. But we're hardly hell on earth. In contrast to other countries, we achieved gay marriage via Parliamentary vote, not through the courts.
