Personal Narrative: Injustice And Inequality

All my life I’ve been told that the world is wrong that there is so much injustice and inequality. But how do I know the world is wrong if I’ve never known it been right?... How do I know the sky blue not violet nor orange nor scarlet? I only know its blue because that is what I’ve be told. All us accept most what we have been told and we rarely questioning why? Why is the world wrong? why is there so much injustice and inequality? Why is sky blue? We have been brought up to accept the ideas of the majority but never fully understanding the truth. While we have differing views of right and wrong but my question can we right those wrongs or do those who suffer injustice and inequality just unlucky?
To be honest I’ve only really just started questioning the meaning luck. I tried to answer this as I was walking to gym one day and I
I’m very logical and if luck exists how I have never got lucky, let me rephrase that. How have I never won the lottery? People will say to me don’t walk under that ladder, don’t put that horse shoe upside down, pick up the penny you’ll be lucky all day and beware of the dreaded number 13. I don’t believe in that. I don’t believe in something from nothing. I believe you have to do something to get something in return.
Most of us will be aware of the principles of karma. Karma is a central belief in Buddhism that nothing happened by accident; what happens to you is as a result of your own personal doing. Buddhists believe that good deeds create good karma and a good future. Clearly therefore, bad deeds create bad karma and a difficult future. They believe that this is why there is so much inequality. Someone said to Buddha "What is the cause, what is the reason, O Lord, that we find amongst mankind the healthy and the diseased, those lacking influence and the powerful, the poor and the rich, and the ignorant and the wise?"
