Hmmm! Deep thought! Hee (plagerism?)
Culture is the by-product of a human race with too much time on its hands. Not required to have to spend all its time contending with survival, the human race devotes time to perfecting craft beyond the requirements for basic existence. Art and culture forms as a result of this 'dallying'. In the same manner, efficiency has the same effect as the need to survive; in the human race's pursuit of speed and economy, time-wasting activities are cast aside in the name of ruthless efficiency. The arts and the culture thus become de-emphasised and people lose sight of the finer things in life.
In countries such as Singapore and Japan where clockwork efficiency is the norm in all aspects of life, every second counts and it becomes unacceptable to waste even 20 seconds on something deemed as non-productive. The subway trains arrive with clockwork efficiency at 3 minute intervals, and in Japan a late freight of train warrants every commuter a letter of apology issued by the train operator. Taking a break from work gets frowned upon; day in and day out life is an endless rat race, each trying to out do the other by finding the swiftest and most succinct way to complete a task. Life becomes an endless cycle of rushing to wait and waiting to rush.
The human mind is a flexible and free entity, and this cycle of efficiency becomes a restrictive cage which the mind tries to break out of. Being late for non-essential functions become a fashion; punctuality and being early is seen as wasting time while one waits for others to arrive. It has become an ingrained part of the society's culture that one accepts it as part and parcel of life and think little about it. Personal time is cherished, chores are shunned and all semblance of regularity is avoided in one's free time. Commuting and living in such a city and environment becomes stressful, and the direct cause is the efficiency.
