Thank u for sharing ur thoughts about this, I have a similar opinion, I don't think one should be sad that he don't have as much money as the richest man for happiness and living securely is what counts, however that does not mean I don't believe that people should work more , better if the work he does he makes it into a hobby or passion to earn money .
Life is weird having too much money encourages it being spent buying things that will not make one happy or even just the workload to keep it up is stressful.
