In all its fairness... I have some questions

It looks like this world and life thrives on unfairness, making the term "deserve" irrelevant in almost all the contexts I've come across.

We don't give to where we take from and don't get from where we give to.

For all the fairness lessons we have imbibed over time, guilt is the outcome of this unfair scheme.

Can we control and bring fairness to this world?
Would it take an enormous heart with lots of efforts to bestow fairness this world deserves?
If, "We don't give to where we take from and don't get from where we give to" is true, then do we at least have the power to choose where to give and be sure of the consequences?
Should we choose to give to the parched as against the ungrateful?
Should we give back to where we took from?
Some of us are givers and takers and some of us just stick to one of the two.
Is our give or take pattern a compensating tactic as we feel subjected to fairness transactions we do not have control over?

I do not have answers. But I think it's is interesting to observe, analyse and learn from all the sweet and bitter experiences of self and of others. And if there are inferences that can be utilised to solve some of the big problems this world faces and in turn bring fairness, then we've done our bit living on this planet.
