Just In Time

Does “just in time efficiency” fit human demands? Most business ventures require 24 hour a day use of the investment in equipment and labor to compete for the ever shrinking profit. Historically humans adjusted to Mother Nature and lived with her cycles. Today we have a man made environment that eliminates bio rhythms and replaces them with machines. What is it to be human and what is happiness from a perspective of human biological subjective view? Does the mathematical view of capitalism or communism fit the whole human ideal?  It seems humans are not consistent and take different stands based on emotions which have many causes.

I think we need to learn more about what it is to be human before we completely alter the human environment.
