Look at an early example of radical change. When Henry Ford invented the impersonal assembly line, he made cars cheaper but in the process, eliminated responsibility for the quality of the product. No one since one person puts a seat in, one person puts a tire on, etc. With no identity with the product and a single, boring task at work, the individual lost the meaning and satisfaction in work, all though the growth of this new technology. In it, he portrayed this Brave New World where every facet of life is planned for and ensured by the controlling financial state.
Citizens are replaceable.
Citizens impulses and desires are controlled and indulged. Workers are encouraged to take drugs of every sort to keep them happy. Failure to take the drugs can result in conviction of drug evasion. They produce and they consume. The individual is unable to even think of a different world than the one he is fed.
