Why would the third estate want votes to be taken by head?

The Third Estate wanted votes to be taken by head to ensure that each individual vote counted equally, rather than being overshadowed by the privilege of the First and Second Estates, which were traditionally given more voting power. This approach would provide a more democratic representation of the populace, reflecting the growing influence and demands of the common people. By advocating for voting by head, the Third Estate sought to establish a fairer political system that recognized the rights and voices of all citizens, rather than perpetuating the hierarchical structure of the Estates-General.
