You’re only able to choose two options, how is that democracy? I thought democracy was about being able to choose anyone you think is suitable to be a leader, not one of two pre-selected people. At that point, it’s not much different to a one-party system, just with two people rather than only one person.
I disagree slightly (maybe pedantically) about our political system. That was explicitly designed by men we can name. It has since been influenced by other forces, and much of its original intent has been subverted. But it didn’t spring into being all by itself.
Economics I agree. While there are and have been forces attempting to guide and influence the economy, it’s always been generally out of the control of any person or group of people, short of command economies.
Both cases put the lie to the phrase, “the purpose of a system is what it does”.
