Well some luck is indeed that. If you were born in the United States for example that makes you likely luckier than some people. By luck I am saying POSITIVE outcomes of chance.
It cannot be avoided.
If you and I are standing in the same room and we each can move at the same speed if you pick a destination point in that room one of us is guaranteed to reach that point first unless the point happens to be equidistant from us.
Thus the person that is closer happens to be fortunate, lucky, or in the right place at the right time in that particular instance.
It isn't something to fix. It just is.
Agreed... but with one caveat: even an equidistant opportunity can be won or lost intentionally, when the competitors become aware of the opportunity. Distance can vary, as you rightly point out, but we are capable of gaining or losing ground with preparedness and hard work. So I suppose it's a bit of both.
Yes the equidistant thing is simply a PROOF that there will always be unfairness based upon factors that cannot be chosen and cannot be FIXED and PLANNED for. It is essentially an easy way to disprove the concept of Equality of Outcome. Equity is Equality of Outcome as well so it is a lie. It is an impossibility. We can strive towards Equality of Opportunity but that is very different.
