Orwell believed, and Goldstein wrote;
” …a hierarchical society was only possible on a basis of poverty and ignorance. ..”
It was the odd thought, contained in Goldstein’s forbidden book that it was not wise to keep the masses in poverty by restricting the output of goods, goods would be produced, but destroyed in war.. Economies were allowed to stagnate, much of the population kept half alive by State charity.
War was for destruction, not necessarily of human lives, but of the products of human labour.
War were to destroy what would make the masses too comfortable.
The goal was to have the people struggle to survive, struggle to obtain simple products, their minds distracted from reality.
