English translation:
The only reason that we are not completely enslaved and we have salaried work is because the "elites" discovered that it is far less profitable to have slaves than to have workers.

Think about this: with slaves, you have to feed them. You have to provide them a home. You have to care for them minimally so that they don't die on you. All of that so they can work poorly and without motivation because they do not have incentives.
It was already evident from ancient Rome that owning slaves was not profitable. If you are going to continue having slaves, they are going to work as little as possible.

But of course, if we perfectly gaslight them and convince the whole population that they're now free, they now pay for their own homes
...with great difficulty, because in 90% of a country's land it's prohibited to construct a house. This way, they're all crammed together and controlled in large cities.

Then they pay for their own food, also with great difficulty because it is quite expensive.

Governments now ensure that massive inflation is created by printing money so that nobody is capable of saving and we always make it to the end of the month... but just barely.

And the best part: you promise them that if they work hard... very, very hard, they will be able to escape from their wage slavery.

And thus, in this way, they would strive as if they were working for themselves, when in reality, they are paying more than half of what they earn in taxes to a criminal state, making others rich, and with the little that remains for themselves, they spend it on survival, on living poorly... but always with the perspective that perhaps, one day, they will be able to escape the hampster wheel.
