Here's my 2 cents about the topic:
Moral really adds depths to stories because it's a logical extension of emotions as opposed to pure rationality (and a story is supposed to raise emotions). The feelings of justice and injustice are social animal instincts (there's an experiment about rewarding monkeys unequally for the same task). Since emotions are personal, moral is subjective.
For instance, if you have to sacrifice a life for another, how do you weight the values? Is there a purely rationale reason for saving a trout over a salmon? There's no real answer, but only pretexts that are guided by feelings. For most people, a human life is more valuable than any other animals because they are emotionally involved (empathizing with the life at risk).
That said, as we move through time, society truly seem to yeet out moral.
Originally, civilization exchanged goods and service through credit and trust between people who know each others. Then, the advent of market created an impersonal place where maximizing profit and purely pursuing material goods were the only things that mattered. Religion grew as a counter movement to remind humanity that material goods weren't the only things important. It aimed to create a long term environment of peace, but economy and human greed kept growing in power without the world taking any good turn. With the progress of science and the hypocrisy of corrupted of religious institutions, their messages lost credibility.
After destroying everything left of religion and morality, we've reached a point where the profits of company's owners matter more than human life. This systemic moral bankruptcy seeps into the individuals, especially in China. The world hurts you, so you hurt back the world. This is the level of personal morality and justice they're grasping onto.
Looking at the food-processing industry across the world gives a grim outlook on the state of morality in this world. In Europe, companies sue organizations that disclose the carcinogenic components in their products because 'it hurts their profit, and the ingredients don't even kill that many people per year.' (not making that up, it was the CEO's lines during an interview lol) In the United States, simply looking at Monsanto is enough. And in China, baby milk is tainted, your food is dyed with toxic chemicals, meat blended with cardboard, cooked in gutter oil, grown with lean meat powder, and injected with water to increase its weight.
When you think about it, the global market has become like a giant anonymous place. Left alone, the concern for maximizing profits leads to horrible things: counterfeit products, long-term health hazards, and planned obsolescence.
What do emotions tell us about waste? About all the food and products destroyed purely for the sake of driving the price up? Imagine all the misallocated resources that were diverted from humanity to create and destroy those things.
The government sometimes beat the companies into the lines. But more often than not, it yield to the power of money.
This immorality for the sake of profit pervades into every levels of society. Because it will do its absolute utmost to turn people into the cogs of the market to enrich handful people. The inflationist money policy and the education of children (things such as student loans) are good tools to bind the oblivious citizens to awful jobs for the sake of sustenance. Inflation will devalue savings while incentivizes people to work new current jobs with updated wages. Student debts and mortgage that appear almost like necessary steps of life will crush people into jobs as they have to pay back their loans.
According to Maslow's hierarchy of needs, people seek: physiological goals (food, wate, sleep), safety goals (home, security, stability), belonging and love, self-esteem (achievement, status), and self-actualization (giving to the world the maximum value in a personal way). People aren't blank slate. They come with their own set of strengths, weaknesses, and values. And self-actualization requires individuals to have a rich inner understanding of their own self (to trust themselves, to follow through their mission, and to know their pitfalls). But rather than nurturing people's strengths to bring the best to the world, society would stiffle their potential to add them to their pool of desperate job seekers (through the means of the previous paragraph) and keep them worrying about food and home.
A company's goal is to extract maximum value from their employees. As a result, they must pay as little as possible. It means that they need a large enough pool of job seekers that are desperate enough to work for them for little wage.
Once again, stealing from the greater good to enrich the pocket of a fews. Those entities grow powerful enough to fund political figures, who then have to fulfill their part of the deal by selling their own country and people.
In conclusion, if anyone has the vague impression that moral has left the chat, you're not the only one.
On that note, I recommend the game Library of Ruina which is a story set in a dystopia where humanity has exhausted all the energy resources of the world, but have harnessed supernatural singularities to thrive. One of the theme is about living in a shitty immoral world, and coping with the feeling of absolute helplessness in face of society.
