"The real reason this could never happen is a reason you’ll like: they are simply not capable of it. They suck too much. And it’s just a biological fact—you can mutate bad ideas, but you can’t mutate suck. Huge sighs of relief are heard all over Berkeley."
Problem: Berkeley also sucks too much. Haha, oops.
The design for America's government calls for 0 lords. No workable government can be formed using 0 lords.
The nearest workable design to America's government calls for 100 lords where only 10 are available. Even if we imagined they fully exploited the available lordship resources, the system would have to adapt to having 90 non-lords in lord positions. It would attempt to need only 10 lords. These changes would make the remaining 10 lords uncomfortable, and they would leave. Lords have options, by definition. This is why the design calls for 0 lords.
The aristocratic population can roughly be modelled as a constant. Only the peasant population grows. World population
has decupled in the last 200 years. Indeed, perhaps saying there are 10
lords for every 100 demands for a lord is optimistic. Perhaps the last
time there were enough lords was about 1300, meaning you're looking at 5
at best, give or take differential casualties in WWI. If education is a
factor, 1 or fewer.
Although you can find a few lower nobles (barons or knights) born to
the lower orders, you will essentially never find a duke or prince born
into a peasant family. Even if you did they would go insane from
loneliness and total dearth of challenge. On the plus side, even in modern times, the four horsemen are deeply prejudiced against the peasants. Sooner or later the problem will solve itself. We don't have to wait for the glacial aristocratic breeding cycle to catch up to the peasant's head start.
America's government is actively hostile to lordship, because the peasants are jealous and insecure. In other words, bureaucracy is about covering your ass and never taking responsibility, which gives hives to most real lords.
There are some psychopathic lords in the workings anyway, which allow it to sort of function. Turns out psychos are psychotic, so only the parts directly serving their sadistic amusement get maintained. For example, working ""for"" the IRS makes graft especially simple, and as a result it runs smooth as butter, even though tax receipts are almost meaningless to USG's budget. As for the rest, the peasants LARPing as lords create problems, because they can't think for themselves, and then desperately, hopelessly, try to patch them up. You can see the results in a newspaper. If you're into that sort of prurience.
'Diversity is our strength' => 'Let's try to steal everyone
else's lords.' Problem: the lords don't want to come. They're already
living large in their own countries. America offers them more money in
exchange for less status. Yeah, good luck with that. (And the system
can't use them even if they did take it.) Basically, you get bastards
and wannabes. Not only that, but due to Fascism, you can't filter out
the lower orders. Peasants, man, I tell ya. Meanwhile the psycho lords are allowing it because strangers and aliens vote democrat. Makes the elections almost look honest most of the time.
In some kind of prank by Fate, many of these peasants are sharp as a tack, and would be more than enough if they could only break away from their irresponsible bovine herd instincts. However, they can't. A smart cow makes smart milk. (Drinking it makes you feel smart or something.) The cow cannot be the lion. No policy or ideology short of Flood-level divine intervention can prevent America's auto-buggery.
It is darkly amusing to see alleged rightists worry about the birth rate on other continents when the birth problem was insolubly bad centuries ago. Certainly you can argue that these peasants are worse than those proles or whatever, but the Titanic is already listing. No sane lord is stupid enough to take responsible custodianship of the stinking, sinking wreck it pleases America to call a country.
