how should the world’s economy develop? what companies should be developed? how should the profit be distributed? should it be illegal for companies to make a profit at all?
(note that i think that it is generally unavoidable that some companies make some profit, the grey area on the image of the supply-demand diagram (or rather quantity-price diagram) is the profit, and that would only be zero if all companies have exactly the same production costs per unit.)



It sounds like you do have an interest. The idea you are referring to was articulated about 150 years ago. If this is the first you’ve heard of it, you’re missing out and I encourage you to explore the ideas more.
And this conclusion you’ve arrived at is a great articulation of the core philosophy - the material conditions of our society produce the ideas of that society. We have the ability to produce so much but we don’t distribute necessities reliably and we don’t distribute surplus properly, this our society is marked deeply by a need for excess. We don’t have to go around changing people’s emotional attachment to excess or their feelings of scarcity, we have to change the distribution of our society’s production and the ideas will follow. This is quintessential dialectical materialism.
You’re not alone in your frustration, in your distress, in seeing what you’re seeing. There’s been movement on this for over a century with people writing tons of essays, books, articles, analyses, and screeds about it. Entire nations have been transformed by revolutionary movements using these ideas as their foundation.
