As a child, textbooks and teachers have taught us that hard work begets good luck. That is, no one comes into the world with luck, everyone has to make their own luck. The more hardworking and the more serious he is towards his work, the more likely he is to succeed. But there are some people around who look at them and think this saying is not true. Around me, I see many such daily wage laborers, rickshaw pullers or agricultural laborers, who remain at the same position from which they started their life even at the end of their age. It's not like they don't work hard.
A day laborer works for around 12 hours non-stop and in return they get a small amount of money which they spend in various ways. Here my question is why they are not able to change their fate after working so hard. In this case you may tell me that he is a daily wage laborer or he is a rickshaw driver that is why he is not progressing but he is focused on his workplace and he is working there with full focus so why is he not changing his fate. If a rickshaw driver or a day laborer wants to but cannot become a doctor or an engineer, he has to focus on his profession. What do you say about his change of fate?
Here's the thing, we all have different ways and manners to actualize our desires and how we want ourselves to fulfill our so-called "destiny". To some this involves becoming very rich that you don't have to worry about a single moment in your life about money anymore, to others, it's plain old working, regardless of how much they are getting paid and how often.
I had an office friend back when I was still working in cubicles who's very happy that she got the job doing taxes and general accounting for the company, she said this is what she's dreamt of ever since she was a kid. I personally was appalled and shocked cause I don't wanna live the entirety of my life in a cubicle working in front of a computer for hours on end. And yet there she is, always eager and happy to work, always performing her tasks splendidly, all that shit. What I'm saying is that for a number of people on the situations you have talked about, it could be what they were really dreaming of from the day they grew consciousness, and as sad as it sounds that's how they get their kicks, and we can't say no to that.
Of course there are people forced into circumstances, people who find themselves trapped in shit that they didn't even want to be in in the first place. But we already know about those guys.
