Reference to the column on "The Contribution of the Haredim."

Mainly in relation to what you wrote, quote:
I have no doubt that every honest Haredi person feels distressed, as it is clear to him that as a society they are behaving in a parasitic, immoral and distorted manner. Therefore, any excuse, no matter how flimsy, may or may not help him come to terms with his conscience.
 
On cognitive dissonance and the feeling of immorality among Haredim.
There is none. Does not exist.
I'll explain: Imagine a child born into a family of musicians, the mother lectures and writes about Bach's music, and the father plays Bach in concerts.
A picture of Bach hangs in the living room. From the age of 3, he is taught to listen to Bach's music, and at an advanced stage, he also learns to play his own music.
His whole life he lives, breathes, admires, is part of a very large community that admires him, studies in institutions where Bach is the central motif in it.
At the same time, he is exposed to a group that rejects his music. He grows up and is educated that "they" – the bad guys – are plotting to make him a part of them too.
That group has beautiful arguments and logic. But he was educated to label them as anti-Bachus, bitter, and coming from bad motives.
And in any case, he will always have the embracing family, and the supportive (and stressful) community – that will support him. Basically, in the deepest parts of the soul.
Bach's music = Haredi doctrine (Torah, great men of the generation, separation)
The only thing I would expect from our guy is "confirmation biases" (justification. In Hebrew), internal convictions, etc. – to justify his education, family, and community. Basically: his stability.
 
Especially when it has a "Gothic back", in the form of figures such as: Chazon Ish, Rabbi Shach, and the great men present.
From his perspective, in the face of their legitimation, any other claim is a heresy against the Torah itself.
That's the situation.
It is deep, it is rooted, it is common ground.
To illustrate the scale – the municipal elections.
In ultra-Orthodox cities that are largely run by Zewa, you will hear sharp criticism among the ultra-Orthodox residents, focused on the representatives they elected.
And yet, the same parties and the same failed candidates won, and grew stronger.
What brings that Abrech to take a seemingly zozoic step and vote against his own opinion?
Answer: The sense of belonging/being part of a community/demands from the elders of the generation/fear of threats from the heads of the yeshivot, etc.
The issue with recruitment is deeper.
If the election is "a frog he's ready to eat," despite the dissonance with his inner feeling.
In the matter of recruitment, the above affects him more deeply. There he will literally abandon all rationality (and certainly a sense of immorality). He will not look for excuses. And if they are needed – he will pull some swan from the supervisor's last conversation. And that's it.
The attempt to convince (the ultra-Orthodox? yourself?) is, in contrast, similar to the government's plan to change education about terrorism among residents of Gaza and Judea and Samaria.
It won't work. You can starve, deny budgets.
But certainly not to appeal to a sense of morality or rationality.
