Les Classes Préparatoires aux Grandes Écoles

Is there anything comparable to the classes prépas in the US? I read up on some private businesses that help kids prepare the SAT and the like, but I do not know of any American school that admits students based solely on an actual contest.
The other thing about the taupes is that they are basically free, being part of the public education system, and it is technically possible - although extremely rare - for a kid from the impoverished banlieues to get into the best Lycées in France provided he gets good enough grades at the Baccalauréat, and thus have access to, say, the ENS and potentially Fields Medal-tier research, completely free of charge. He might even get a grant from the state depending on his revenue and capital.
IMHO, this is the closest to a meritocratic system there is (or at least that I know of), being that the classes prépas are absolutely exhausting and the contests literally impossible to finish, but the selection is such that only the best get to ultimately enter the schools.
Tell me why I'm wrong, /sci/.

Oh shit is this true? They admit I did think the HPV was being pushed through with a little bit of questionable motivation but I figured it would be beneficial. Apparently it's not worth it.

ITT: we giggle at people who refuse to accept that the halting problem is uncomputable.
Videos like this:
that provide very elegant and visual explanations of the halting problem are downvoted and packed with people insisting that the argument is false.
>H(machine, input) = if machine(input) halts then return true, otherwise return false
>X(n) = if H(n, n) then loop forever, otherwise terminate
The core of the proof is that X(X) has no well-defined behaviour, showing that H is contradictory by nature.
Favorite arguments for why this is supposedly bullshit includes:
>H isn't making the mistake, the dumbass person negating its output is making the mistake. Just don't do that and you'll be fine.
>X doesn't count because it was deliberately set up to make H fail. Why are you so mean to H? H didn't do anything wrong!!
>The argument starts with an assumption (H exists) and my philosophy teacher said you can't do that.
>Who are you to decide what's "correct" output anyway?
>The problem isn't the machine, it's the problem that's impossible to solve. (this one's correct but missing the point)
>I'm a software engineer and I've worked for Google for 15 years so shut up.
Why is this so difficult for people to get?
People with legit trouble understanding are welcome to ask questions and willl be met with polite explanations.
People who insists that their misunderstandings are correct will be laughed in the face.
