alt Hacker News> The statements would usualy be stronger with specific limitations, or an opening for what we don't know yet. Why did it take this form in particular for political system?
It's claiming an empirical fact, rather than pure opinion (cooking preferences) or a fact with a well-characterized theory behind it (OOP, anything physics, ...).
> empirical fact
The phrasing is way too blurry for it to be a reasonable fact. The original quote came from a politician, and how people convey it today are as vague as it was initially.
For instance, thinking for a minute about "who". Who are we talking about and who is judging the results ? When did the experiments happen and what do we actually know about it ? On the "what", What other forms are we referring to ? What period are looking at ? etc.
It would be the same for the theory. Which well know political theory do you see related to this ? Political science doesn't deal in "better" or "worse", and I'm not even sure there is any consensus on the different systems.
IMHO, the more you think about it the stranger it becomes. I invite more people to get on the journey.
