Excessive profit is bad design.

Onur Cobanli explains:
Extreme wealth accumulation represents a hoarding of collective human life energy, as money fundamentally represents time and effort extracted from human lives. While profit enables progress and innovation, excessive accumulation without productive purpose becomes a moral burden on society, essentially storing away years of human life force without meaningful contribution back to civilization. Remember that in the 21st century, to create value added, to earn money, we work, when we work we use our time and energy, this time we used for work to earn money never comes back and is taken from your all available lifespan, as such the profit which is accumulation of money, from one aspect is accumulation of life energy, and excessive accumulation of such life energy is nothing if not evil, but of course sometimes you need a lot of life energy to tackle grand projects, you need a lot of money to undertake big projects, however just swimming and sitting on such money, from this perspective, by deductive reasoning is inherently harmful to society and social wellbeing and thus because it is harmful to society (because you accumulate many people's life energy) it is therefore evil. If I were to call billionaires evil (which I do not, as I think society needs these free variables for they have a distinct value for fulfilling a special function of accumulation of wealth which could potentially be used to undertake great innovations, sponsor art and/or for big investments), the reason why I would call billionaires evil is if they are just like a dragon on their wealth; it is indeed evil to have wealth and not use it towards production, because in most cases any and all production is public good and is giving back to society, so if you just invest the money, that's sort of corrupt because you are not using the accumulated wealth, the accumulated life energy towards production but for siphoning more life energy (even if you would argue that the money you give can be withdrawn and invested), I think you should be super responsible when it comes to excessive profits, likewise excessive luxury could be considered evil as it requires immense life energy to obtain it; it has a moral cost of sorts, but let's be real, who do not like luxury, so it has a distinct value in our society as a motivator, these are not simply subjects for me to just type here but I hope you could think of this nuance, build upon and reflect on it. Profit is not evil, profit allows you to accumulate wealth for which you can use to engage and tackle larger problems, what I am talking here is immense profits, massive profits, that are accumulated but not used for production. Excessive profit is evil.
