HaHaHa,
a "protection" which cost more as 50 % all incomes.

No, thank you!
Either embrace Islam, or pay more as 50 % tax, or let be killed.
The passage in question has nothing to do with jizya; work on your English before attempting to analyze something written in this language.
The jizya is paid by able-bodied males in exchange for exemption from military service and communal autonomy.
Yahya related to me from Malik that he had heard that Umar ibn Abd al-Aziz wrote to his governors telling them to relieve any people who payed the jizya from paying the jizya if they became Muslims. Malik said, '"The Sunnah is that there is no jizya due from women or children of People of the Book, and that jizya is only taken from men who have reached puberty. The people of dhimma and the Magi do not have to pay any zakah on their palms or their vines or their crops or their livestock. This is because zakah is imposed on the Muslims to purify them and to be given back to their poor, whereas jizya is imposed on the people of the Book to humble them. As long as they are in the country they have agreed to live in, they do not have to pay anything on their property except the jizya. If, however, they trade in Muslim countries, coming and going in them, a tenth is taken from what they invest in such trade. This is because jizya is only imposed on them on conditions, which they have agreed on, namely that they will remain in their own countries, and that war will be waged for them on any enemy of theirs, and that if they then leave that land to go anywhere else to do business they will have to pay a tenth...People of the Book and Magi do not have to pay any zakah on any of their property, livestock, produce or crops. The Sunnah still continues in that manner. They remain in the faith they were in, and they continue to do what they used to do. If in any one year they frequently come and go in Muslim countries then they have to pay a tenth every time they do so, since that is outside what they have agreed upon, and not one of the conditions stipulated for them. This is what I have seen the people of knowledge of our city doing." - Malik's Muwatta, Zakah, no. 17.24.46
The jizya is not "50%" of a person's wealth; jizya is determined based on their means and generally takes the form of a consumption tax:
Narrated 'Amr bin Maimun Al-Audi: I saw 'Umar bin Al-Khattab saying...."I recommend him to abide by the rules and regulations concerning the Dhimmis (protectees) of Allah and His Apostle, to fulfill their contracts completely and fight for them and not to tax them beyond their capabilities." - Sahih Bukhari, Funerals, no. 475
The Sunnah is to perpetuate the tax system of the previous regime unless it is too oppressive or does not generate enough revenue.
Yahya related to me from Malik that he had asked Ibn Shihab why Umar ibn al Khattab used to take a tenth from the Nabateans, and Ibn Shihab replied, "It used to be taken from them in the Jahiliyya (pre-Islamic era of ignorance), and Umar imposed it on them." - Malik's Muwatta, Zakah, 17.25.49
