How can the following quote from Ender's Game be analyzed?
"It was not his fault he was a Third. It was the government's idea, they were the ones who authorized it - how else could a Third like Ender have got into school?"
This quote speaks to the controlled future in Ender's Game. The human race is overpopulated and at war; they cannot afford a constantly-growing population, so they limit children to two. "Thirds" are children born and subsidized by the government in the hopes that enough of these children will be gifted and able to learn to fight the never-ending Bugger War. Ender is a third, and he knows it is something that was decided for him; he must survive first in school and then in training without the cultural acceptance that most other children have. Although he recognizes that his life has been formed by others, he tries to make become the best student he can be; this often takes the form of unpopular decisions and sometimes violence when lesser students threaten him. Ender would never have been born without the government needing an insightful battle commander for their fleets; Earth would never have won the War if Ender had been allowed to coast through school without adversity.
