Why did the voting system matter in the estates general

 ANSWER: Palestinians would be Jordanian citizens. 

Evidence: 
Before the 1967 Arab-Israeli War (also known as the Six-Day War) Jordan occupied the West Bank and the King of Jordan made efforts against any Palestinian national identity movement. It was Jordan's intention to remove any idea of being "Palestinian" from the West Bank Arabs and instead integrate the land into being part of Jordan, as it historically had been. 

Israel gained control of the West Bank as a result of the 1967 war and has since granted the Palestinians autonomous rule. Without the war the West Bank Arabs would be Jordanians. However many of the "Palestinians" became Jordanians anyway and vice versa. Jordanians are no different culturally, linguistically or ancestrally to Palestinians; they're all just descendants of Bedouins who were urbanized and ended up on different sides of the border when the British and French decided to divide up the land up after the fall of the Ottoman Empire.

The estates general, a general assembly representing the French estates of the realm: the clergy (First Estate), the nobility (Second Estate), and the commoners (Third Estate). Summoned by King Louis XVI to propose solutions to his government's financial problems, the Estates-General sat for several weeks in May and June 1789 but came to an impasse over the first item on the agenda: whether they should vote by estate, giving the first two estates an advantage, which was the King's choice, or vote all together, giving the Third Estate the advantage. It was brought to an end when the Third Estate formed into a National Assembly, inviting the other two to join, against the wishes of the King. This signals the outbreak of the French Revolution.
