i’ll tell you why in a shorter way:
you were born into it it is not your fault if you are born poor it is the kind of family you were given to so it is what it is if you were born rich then congratulations but how you die is what will be blamed on to you
if you still die poor then it means you didn’t try enough or opportunities weren’t made and they didn’t come your way but if you die rich then it means you took advantage of each opportunity and made it your own
Not everyone chooses to become rich in life, We are not equal and we can never be equal, some people are born to become poor and die as poor people that's how God plans for them, some people will be born by a rich family and at the end he will die as a poor person, I this life we have to know that everybody has their faith and what is your faith will always be yours, sometimes life give some of us opportunity to change our lives but not everyone can use the opportunity.
When you are blessed don't think you have to make it because life can change in a minute, if you are born into a poor family that doesn't mean you can't get rich and if you are born into a rich family that doesn't mean you can't become poor, many people blame their family for their condition instead of working hard and make the family proud to have them as a child.
I think that you have a point in what you are trying to say here, but I believe that as humans that we are, our destiny is in our hands, it all depends on how we managed it, if you are born into a rich family and decide to mismanage it, you will definitely liquidate in asset and at a point you will became very poor but if you manage it well by not spending more than you earn, you will continue to remaining at the top, but being born into a poor family, you need to work hard and smart to pull yourself out of that deep shit because it's not that easy to break out from a generational poverty.
Then on the aspect that some people are predestined to become poor in life is what I refuse to accept, God has a better plan for all of us bro.
I believe that everyone has a bright future if they work diligently and smart, though you wouldn't be that too wealthy, but you will definitely live a comfortable life, not in abject poverty, that's why I believe that it's all depends on how we work, because in life, things might not be working for you because you are actually doing the right thing, but the wrong way, so we should try our possible best to do the right thing the right way and also the right time, because the timing is very much important.
