We'll never said their democracy works it's just theirs was the first alternative to govern a nation that the status quo of monarchies since Roman empire fell. Fuck American democracy is clearly not the democracy I wish to one day have, but it did provide stability in leadership relative to monarchies since the leaders (in theory) are chosen by a supportive people for their ability to lead and not because someone fucked had a kid with their cousin and now that kid is destined to lead.

There are many government systems out there, unfortunately some are bad, some are good but I do not know of a one size fits all.
