The repeal the 19th meme is funny but now I'm not sure that is as much of a problem.
The property requirement meant that only those with skin in the game were the ones who got to decide who governed. Without it we have paupers and indolents with the power to spend money that they did not earn or pay.
That inevitably leads to the death spiral from the famous quote:
A democracy cannot exist as a permanent form of government. It can only exist until the voters discover that they can vote themselves largesse from the public treasury. From that moment on, the majority always votes for the candidates promising the most benefits from the public treasury with the result that a democracy always collapses over loose fiscal policy, always followed by a dictatorship.
Obviously no political movement can form based on this principle since our current "conservatives" are too spineless to even fight for voter ID requirements. But at least it is within the overton window allowing for public discussion.
There's also that warning from the Family Compact (that I actually remember learning about in school) about how they thought democracy would devolve into the equivalent of a popularity or beauty contest.
We were supposed to laugh and scoff at their elitism, but I fail to see where they were wrong.
And maybe the big flaw of Western feudalism was in allowing titles to be bought by the merchant class.
And maybe where we all went wrong was in allowing the merchant class to have a say in anything.
Merchants can be very useful at distributing things to the public. However they should not be praised if they do that well, it's just them responding to public demand.
The worst case is when a merchant expends public demand, but wants more so they manufacture demand instead. Historically this is the "snake oil salesman" but in recent years it's just basic advertising and social engineering.
