Marx and the Slave Mentality

Is there any clearer expression of the slave mentality than the systems of Marx and Engels? Well, perhaps there is, but anyway.

Man exists as a digit within a great mathematical equation, the equation being apparently life, and the entirety of the individual life or digit is his movement within the equation. The individual is an individual in his essence, a single point, an ego; transcendence, God are asserted to be non-existent, and yet for this individual to act as the digit within the economic-historical equation that is existence and to achieve 'success' within it, according to its values, to ascend towards its upper echelons, is apparently proof that he must be removed from the equation, annihilated. But why? Didn't he satisfy the nature of reality- the equation and its digits? He did, and that is precisely his 'sin': the ego behaved as an ego. Though how, in the absence of an intrinsic moral order, one might wonder, can it be a sin for an ego to behave any way it likes? What's there to transgress? But leaving that aside.

We must change the nature of the equation, as given man's nature as an ego he will behave as an ego, and this is undesirable for the lesser egos. So we must have a new equation, an imposed form of life- and what is life but the form we make of it- so we need an equation in which he doesn't get to behave as an ego.
"But isn't an ego is all there is, so how can he not behave as an ego?"
As already said, by changing the nature of the equation. We will make the equation so watertight that he can't but behave unnaturally, not as the ego that is his nature. We will create the perfect, unnatural, artificial conditions in which he cannot but behave in the perfect, artificial manner unnatural to his natural egotistical being.
"Oh what a beautiful ideal! But wait, who are they who control the equation, change its nature, or rather impose the new one? Surely they can only be more egos, and why won't they behave as egos, now that there's nothing to stop them? They are now the foremost digits in the equation after all, and isn't it the nature of these digits to wish to remain the foremost digits? This being the nature of the digit and the reason the previous equation was unsatisfactory- digits within the equation behaving as digits within the equation. Surely the digit will now behave in the manner natural to the digit, and so woe to the lesser digits."
"You forget about self-sacrifice."
"But how can the digit sacrifice itself? Didn't you say the digit is all there is? All this infamous transcendence illusory- the digit is all."
"We take on the burden of knowledge. Let that be enough for you."
"And what if a digit or person refuses to exist within the new equation?"
"The equation is life, and so naturally a digit that doesn't exist within the equation doesn't exist. An equation only contains that which it contains. It is stupid to treat as real, within an equation, digits that don't exist within that equation."
"But what happens to it so?"
"You're insisting on treating this non-existent digit as real. It may have existed within the old equation, but it doesn't exist within the new one. If you must, consider the digit to have been erased."
