What's happiness?

What's happiness?In older times,there was a wider gap between rich and poor when a load can enjoy gorgeous life surrounded by many subordinate.I wonder,however,if such load really enjoyed happy life because they didn't have any convenient tools like pc nor TV sets at all.When we look at it from closer span of time,in 1960's we didn't have any advanced electronic devices like DVD nor digital camera.What I want to say from such truth is that there is no point in seeking for wealthy life by making profit since in future life we'll be able to enjoy better life with more advanced devices.Besides,wealthiness cannot be obtained not only by money but also by one's wealthy and healthy state of mind.As our society becomes materialistically saturated,the gap between rich and poor seems to be becoming narrower,mostly widened by political or economic reason.

Anyway it must be one reason why young generations lost their ambition to get promotion like we used to have in economic growth period.
