The concepts of being ‘Equal’ and of being treated with ‘Equality’ are different and not understanding the difference between them leads to a great sense of deprivation and unhappiness.
Equality is a matter of opportunity and consideration and should rightly be insisted upon and ensured for all, while Equalness is a matter of Condition, of Circumstances and of Capabilities, and as even the Almighty has not deemed it fit to provide it in the same measure to all, it is not something to expect or demand.
Better understanding and appreciation of what one has, leads to greater contentment and happiness. Perceiving Wealth as not only assets and money, but also, as leisure and family time too will help.
